I can understand people wanting to get paid for their videos but I can tell you that even for me on my channel revenue from ads placed by YouTube is minuscule. I'm a small channel by YouTube standards for sure but here are my numbers for 2017 to give reference:
Views: 423,684
Watch Minutes: 2,256,329
Estimated Revenue: $702.70
So you can see that even with just under half a million views I still made less than $1000 for the year in ad revenue and YouTube Red revenue.
If you're wanting to try to make money off YouTube videos the way I would look is to sell sponsoring ads for videos or ad space in your videos from companies. Handling this affair yourself will net you more income from your videos than YouTube paid ad space.
