Why is it so much more amusing to watch someone play a video game than it is to play the game itself?

I mostly play fighting games and watch and often watch people that are way better than me to get more info about the characters they play, the matchups, and general strategy I can use when I play myself.

But for entertainment? I mostly care if the content creator is funny, and not really what they play. God only knows how many hours of DBD, a game I have zero intention of playing, I've watched because the people I liked watching were into it.
