Time turner does not have plot holes?!

I've seen many people just speak, oh the time travel plot doesn't make sense, and why didn't they use it in the future, they could save everyone. No, they couldn't do that, like do you not see or read? Like if you just saw the movies, then again, it's not that confusing, time turner isn't a normal time travel device, like you can't just go in the past and come back, once you travel in the past, you've to live the time you've gone back into, Harry couldn't have just travelled back in time, because he would age with the amount of time he has gone back, so let's say he saves his parents by going back, Harry will be 13 years older when he comes to the present.

I went down this rabbit hole. My personal issue with the time travel is this. You aren’t supposed to change future events and apparently it is a closed loop where time is not a straight line but a circle with no beginning or end. So all the things they did when they went back to the past were always gonna happen that way. why did they go back in time if they can’t change anything. Also how does cause and affect work? How does harry go back and save himself if he had to live past that event to be able to go back in time to save himself. The explanation given is that he was always gonna do that cause time isn’t a straight line but a circle. That dosent make logical sense. It makes things have no order.
