Saturn is NOT the only Planet which has Rings -
Jupiter and Uranus also have Rings - just not so notieceable.
It is an odds-on chance that ANY Gas Giant or Ice Giant will have Rings - and lots of Moons.
These Planets all have some of the characteristics of Stars - pulling in debris and forming their own Acrretion Discs.
Actually - they are also like Stars in another way. They all Radiate more Heat than they recieve from their Stars - the heat is actaully caused by their own gradualy compaction, generating heat by compression and friction.
If they get massive enough, they will start to glow - and may start to become Stars, even if only Brown Dwarfs.
