Light travels through glass (fiber optics) at 2/3 of the speed in vacuum. So as long as you are skipping some ground links by doing similar length links in space it is faster. Low altitude orbits mean that the hops up and down can be compensated by faster hops across. That all of course is not there yet and depends on Starlink implementing the cross sattelite links.
