Things do not cease to warp reality simply because they exist within it.And their ability to do something has no bearing on their ability to recognize its a consistent part of their reality.
I actually do know how to fly a plane and have done so myself, but even if I didn't, I don't need that knowledge and experience to know planes exist and aren't some supernatural thingamajig.
Likewise, unless we're talking a low magic setting where magic is both low key and relatively obscure (which is not what DND is) your average person doesn't need to be a wizard to recognize magic as a thing. But even those low magic settings, the apparent supernatural nature of it only extends as far as ones direct knowledge of magic does.
A Muggle in Harry Potter would see magic as reality warping at first, but given enough time and exposure its just reality, because of course it is. The Muggles ignorance of the existence of such things in their reality does not put those things outside the bounds of reality.
Not all that different from the trope of modern technology being effectively magic to people from earlier ages if you could travel back in time. An ancient Egyptian would have no context or even language to begin to describe a cell phone, nevermind the intracacies of how one works, but that doesn't make the cell phone supernatural.
Technology is not exempt from the capacity to warp reality.
More than any of that it's not binary. It's a matter of scope and degree.
Even with continuous exposure to Harry Potter magic, nonstop, their entire lives, Maggie's would recognize that wizards, on average, have far broader scope to manipulate reality to a far greater degree.
And high-level wizards in Harry Potter (whatever that means) even moreso.
It seems like your bar for "reality warping magic" is "literally rewrite everything that exists everywhere in a setting".
My bar is significantly lower than that.
