Unity is a platform where coders can make their own games, much like a simpler platform like Scratch. It's one of the more modern platforms nowadays, and that's where a lot of beginner developers are starting their careers.

And to your other question, no it will not affect you in any way. You will be able to play with others normally as before. It's that the devs are testing out newer and better GUI and stuff, with the release of ToS mobile. There's no need to worry :)
