ATC talking to players or LIVE traffic when other players are disabled?

I’m flying on my own with live traffic (real world airplanes) on and other players off. The ATC is talking to a lot of planes, see screenshot. Is this ATC talking to the real world planes, if so, how does that work, how do they simulate that? The names and instructions suggest it’s not talking to real players. I’m confused xD

@JaPPa They are most likely to talk to real airplanes.

And they can simulate that by collecting data about the flight and where it’s going and where it departed from and it’s flight path.

I never heard the ATC talking to another player. But idk if that is how it’s supposed to work or the reason is no one use the ATC.

It is SIM ATC, as the phraseology is non-standard, bloated and faulty.
