Creator gets 55% of ad revenue, and 70% of direct contributions like superchats. Premium revenue is shared as well. Ad-blocked views count for analytics but not in ad impressions.
It seems to me that YouTube would serve ads on any channel, not just those part of the YouTube Partner Program, but the % revenue share isn't published for non-partners it seems.
It's all there, no need for rumors and hearsay.

From the first link:
> I'm not a YouTube partner, so why am I seeing ads on my videos?
> YouTube may also place ads on videos in channels not in the YouTube Partner Program.
Doesn't this mean that YouTube is earning money from ads placed on videos where people don't get anything from the revenue?
