If gravity works by pulling everything to a single point (planets centre), then what’s keeping the rings on their specific axis? Shouldn’t it be an even layer of debris around the planet?

The material in the rings has momentum, so it stays in orbit, it could clump together and form a moon. But Saturn is very massive and would apply a large shear force on that moon. That has slowed formation, and maybe prevented it, we can check again in a million years.
