If you're not interested in the actual flying part then I'm not sure if it is worth it?
I think the path for most people is first they get interested in flight simulation, frequently in the context of flying airline jets. They start learning how that airliner works. How to start it up. How to program a flight plan & performance figures into it. How to use the autopilot. The concept of SIDs and STARs (departure and arrival procedures) (and again how to program them into the plane) and finally learning about all the different types of approaches like an ILS approach which allows the plane to break out of extremely low level clouds (think 200 feet, sometimes less!). And finally, how to perfect landings.
They do all of that usually offline. On their own, or with some plugins that inject fake AI traffic to make it a bit more immersive.
Then finally, once they have a grip on most of the above, then they hop onto VATSIM to add the challenge (just at start) and fun of talking to ATC and listening to other pilots. It just is really a great immersion factor to know there is another human being operating the plane that you're taxiing behind.
But if none of that initlal stuff sounds very interesting to ya then (1) no problem!! It's understandably not everyone's cup of tear but then also (2) probably not worth getting into VATSIM.
But if VATSIM on its own kind of intrigues you then maybe you can live vicariously through people on Twitch playing MSFS on it, or YouTube searching "msfs vatsim full flight"
