I have no idea, but I'd assume the opposite. Twitch partners seem to make up the vast majority of streams from what I've seen. I you take any game and scroll down, there are so many people with 0 to 2 viewers (probably another open tab or a friend) that are generating video that would be stored, but not generating revenue unlike something like a large video game tournament.
I'd guess it's something like 99% of content is seldom, if ever viewed, but I have no clue.
As for videos over 100 hours, it may be mostly top streamers.
