If you teach yourself, then it will probably happen. I've been playing keyboards in rock bands live for about 25 years, and my last lessons were when I was about 9. So I'm essentially self taught.

I also tried playing classical songs for fun, and did pretty well but there came a point in difficulty where I just couldn't play them. And it wasn't for lack of practice time, my technique is just not good enough and won't ever be.

But most people won't reach their ceiling. I also play guitar live and I'm very far from my ceiling in that instrument - a nice way of saying I suck
