The simplest answer as to why Saturn has rings and what they are made of is that the planet has accumulated a great deal of dust, particles, and ice at varying distances from its surface. These items are most likely trapped by gravity. The rings appear because of the wavelengths of light reflected by these rings of debris.
Some scientists speculate that Saturn may be too big. Its gravitational pull is so strong that it has been able to snatch debris from space.
one theory state that/ this debris r it's moon(like our moon) which was collided each other during the planetary formation .as u say gravity of Saturn is high so it hold many moon as Jupiter

Saturn is not the only planet having rings around it, the outer planets (Jupiter/Saturn/Uranus/Neptune) have rings around them, but it is faded whereas the ring around Saturn is bright.
