I get the explanation that they have gravity and things are attracted, but why is it in a ring rather than a sphere? why do things from one AXIS get attracted but not from other?

Every orbit is centered around the center of mass of the system. So you can’t have more than one orbital plane without them crossing each other. So when you have a bunch of material swirling in from various angles, it all collides and averages out into an orbital plane that is the average of everything falling in, and you end up with an accretion disk.
