There's a difference.
If you try to join a server, and then immediately it says "you are banned" before you hit the lobby, you're ID banned. You'll have to get a bypass / id changer from someone on this forum. Good luck w/ that one, as no one here knows you, and.... Yeah, you're fucked, bro.
If you try to join a server, and are successful, and are in the lobby, and are banned once you get in game, that is a BattlEye ban. And you are then fucked. There's no way around it (that I know of).
