That's not true. YouTube gets 45% of the money your videos generate and you get 55%. If a viewer buys a YouTube subscription then 55% of the price of that subscription gets shared among the channels that the viewer watches.
I actually forgot that YouTube had rolled out the Join button. You get 70% of the revenue of the Channel Membership (join button). YouTube gets 30%.
