Its basically a paradox, which I think is what you mean when you say they can't change
anything. You are right, of course, but are not really saying it right. They can change
things, but its something they were going to do anyway, because they are only messing
with themselves.
No. But yes. You're trying to overcomplicate it.
The Harry Potter universe, the one that is experienced in real time, is a compression of all possible time travel events into a single, master, timeline. Anything that will ever happen re: time travel has happened and has been flattened and incorporated into the master timeline (The one we experience).
Therefore, it is literally impossible for anyone in the Harry Potter to change the universe through time travel because whatever they did had already happened and was already a part of the "real" timeline that everyone experienced. So therefore the only thing they can do is whatever has already happened.
The only reason it seems (to Harry) like he was able to change the past is because he didn't realize that he was the one doing it in the first place. but everything they did had already happened in the main timeline, they just weren't aware of it.
I'm not saying it's perfect or even a particularly great example of time travel theory, but it's how TT's and time travel in the HP universe are shown to work.
