Not all galaxies are flat, and the stars in galaxies are sperated by enormous distances.

It's the difference between Saturn and its rings. Saturn the plantet collapsed into a spheroid. The rings are pieces of stuff, not solid. Of all the stuff in the rings were thrown together into one solid clump, it would be a spheroid, too.
