Low earth orbit includes orbits that take from hours to centuries to decay, depends a lot on altitude/apogee/perigee. Starlink for multiple reasons places satellites in the range where it takes ~5 years to decay, thankfully. Kessler syndrome is real though, and satellites do collide or break apart in LEO.
