The difference I was aiming at is that the offline events are widely understood, relatable and recognized. When you do well in a sport, I may not care one bit about this sport myself, but I understand what a sport is, that it's played in the real world, is competitive, and that you had success in it. Hence, every possible demographic recognizes your accomplishment without question. This is not the same thing as streaming a game nobody ever heard of and having 20 spectators nobody knows. It's not or poorly understood, not seen as a relatable achievement, also not in an absolute sense, and at times may even be seen as an anti-accomplishment: do something useful with your life. You can try to intellectually smudge these two things together as being the same, but that's nothing but semantics. My point stands that online accomplishments are not accomplishments unless they are extreme (I made a 100K from Youtube).
