You are correct. From what I have read, satellite communications using C band (TV broadcast station, Mhz waves) transmissions will be used with the satellites.
Satellites will be used to assist 5G networks, but they're not going to be using 5G frequencies. https://www.rcrwireless.com/20180108/5g/the-role-of-satellites-in-delivering-5g-tag17-tag99

The SpaceX project is called Starlink, and it will use the Ku and Ka bands, which are in the mm wave length. These bands have already been used for satellite communication previously, so it does work. The atmosphere only attenuates the signals, it does not block them. So it's just a matter of transmission power and antenna gain, and the signal can be made to pass through the atmosphere.

Wow. That's a seriously ambitious project! It looks like it's still a few years away though.
While details are lacking, it appears that they plan to make this work by utilizing powerful earth based antennas, mounted to some type of base station. And from there, utilize standard 5G cell transmissions.

So the signal will "slow down" to get from tower to satellite and vice versa but "speed up" again from tower to tower. Call me skeptical, but the only advantages to this will be for AI and not humans.

The satellite transmissions are to connect remote areas, similar to how satellite internet connections work today.
Normal 5G networks use wireless (high frequency) transmissions within their cell zones, and then pass that data off to a fiber optic backbone to move the data to connect cells over long distance. The satellite transmissions will be much, much slower, so I expect they will only be used for 5G cells that can't get a fiber connection.
