Starlink is a low altitude constellation, those satellites are moving relative to the surface not stationary like traditional communication satellites. They're setup in a mesh of orbits at give or take the same inclination just offset in phase so there's some moving north east and others moving south east over an area at any given time. So every satellite will spend a lot of time over oceans just because the Earth is mostly ocean.
