The satellites are extremely close to Earth in order to reduce latency. Traditional communication satellites sit in geostationary orbit hundreds of thousands of kilometers above the surface, this you being that that's many times the diameter of the Earth so signal delay is pretty noticeable. Starlink satellite wiz around the Earth dozens of times a day, but the advantage is that they're only 200 km up.
The disadvantage of all of this is that each individual satellite has a very small footprint, so it's entirely possible for some regions not to have coverage yet as the network is not complete.
