You've injected a very forced interpretation into the Harry Potter series. And you've also let some of your other assumptions color your claims in ways that can be contested.

Lots of cool religious stuff in the Harry Potter stories.
Yeah, religious symbolism is a very marketable and imaginative way to enhance literature. I don't disagree.

One first is that it tells of practical and realistic forms of magic, as like a person can not fly but there could be a type of flying machine which looks like a broom. That changes the magic into some thing possible.
The magic of Harry Potter's fictional universe is depicted as having rules and limitations, but these are expressed as being limited more by imagination and creativity than physical laws. Beginners are taught how to pronounce spells, only to learn that they simply need to will the spells into being with enough practice and effort. Potions have lists of ingredients, yet have fantastical results that are clearly greater than the sums of their parts. Education being a key aspect of the setting allows for greater immersion into a field of fiction that isn't explored well in many other sources of fiction. So it's safer to say that the magic of Harry Potter is constrained by rules, but these aren't the same rules governing real physical laws.

Also the magic comes from a wand and people could conceivably make a wand that works wonders.
At some point, wizards and witches learn how to manipulate objects without the use of wands; casting charms appears to still require a wand in most cases. I suppose the self-satisfying response would be that a wand is a 'focus' for the inherent magic affinity for wizards and witches, and is needed in many cases, but not in others.

Having a love potion is realistic which looks like magic, or any sort of potion can be created to look like magic.
This is the part where you've tried to slide in the insinuation that "science is really just like magic in lots of ways." If you wanna go this route, you have to add so many caveats as to make the comparison trivial.

A lot of religious people (especially Christians) have the mistaken idea that any true miracle has to happen like magic without any realistic mechanism, and that kind of magic is not really the way of miracles. So Harry Potter comes closer to reality then does a lot of the religious mysticism.
Yep, a large population of Christians condemned a great deal of pop culture, including Harry Potter, Pokemon, etc. Whether it was too mystical, too satanic, or just too foreign, the American Christian demographic made its bias known and rightly developed a stereotype that continues to be understood by the Millennials as a form of regressive fear-mongering. I should think it wouldn't matter how the magic in the story is described, the fear-mongering of the 90's and early 2000's was something that couldn't be stopped because Christians wanted to hate it.

As like having a baby is a miracle, and flying in an airplane is a type of miracle, and people breaking the bonds of addiction is a real miracle - and so Harry Potter does fancy kinds of miracles and calls it to be magic.
Here's where your earlier hinting at "real world phenomena is miraculous," takes fruit and you make some rather stunning claims. Conflating multiple definitions of "miracle" only comes off as forced and even manipulative. If someone calls something "miraculous" in that it is an incredible achievement, that's a fine colloquialism. If someone calls something "miraculous" in that it is a source of divine intervention, then sorry, but nothing about the events you describe fits the bill. If someone calls something "miraculous" as
a divinely natural phenomenon experienced humanly as the fulfillment of spiritual law, then that still doesn't fit the bill. Everything we observe in live birth and aerospace engineering is very much natural and even mundane, if we allow dissenting voices to represent their opinion on otherwise completely normal occurrences.

Next if we think about it (as I have) then the discovery that the planet earth is spinning around the Sun at high speed and being held in the perfect position by invisible forces - then that is a by far a bigger and more spectacular miracle than anything told in the Bible, and it is far more magical than anything done in the Harry Potter stories.
You really jump into deep water with trying to call everything physical "miraculous," because tying together Harry Potter magic with the idea of "undiscovered scientific findings" causes the average Christian to believe that miracles, being outside the scope of science, are perfectly normal and reasonable to believe in. And you sprinkle in claims about mundane events and call them miraculous, to boot. You've stacked the deck in a way that only a Christian can, but you'll find that this is all unconvincing and laden with religious assumptions if you look at it from an outside perspective.

Truth is stranger than fiction.
And that quote has been pulled apart over decades to justify unreasonable claims about reality and things that can't be justified. It should be used with caution, not as a means of tying a neat little bow on a post equivocating several different events, both real and fictional, together under the moniker "miracle."
