It is for everyone. They say the event is for GOTY just to indicate that they may be playing some modes from each of the DLCs, not just from the main game. As long as you have the DLCs it doesn't matter how you got them.

It is triple XP for everyone (including everyone on Xbox) for the duration of the event and for all game modes, regardless of whether they actually participate in the event or just play on their own. The triple XP is usually extended through the night or even through the weekend.

There are a limited number of Rockstar devs so not everyone gets an invite to participate in sessions with them. Just set your expectations that you'll have a fun time playing RDR regardless and if you get invited to one of the official sessions, that's just a bonus. I've only gotten into an official session once after several events.
