Why don’t the rings of Saturn and other big planets get pulled into the core by their massive gravitational force?

The ring materials are in orbit around the planet. It's the same reason Earth doesn't fall into the Sun, even though the Sun's gravity considerably dwarfs that of Saturn. Some material *is* lost over time - to various ends - but outgassing from the geologically active moons provides a steady supply of new ring material.
