I'm slowly becoming more and more interested in educating myself on investing once I finally get back into the green zone (hopefully 2020 is the year for that!), so there's this Graham Stephen guy that I've been loosely following lately. Here's the video where he revealed his YT Adsense income:

If you can't be bothered watching, he's made more than $100k from roughly 10 million views in just 30 days.
He often has crapton of midroll ads, so I'm not even surprised he's making so much off of YT ads alone.
He also made a new one a week or so ago, I haven't watched it yet, but if you're interested:

There are a lot of videos from bigger YTbers showing how much they make off of YT ads, but it all boils down to CPM and number of ads, which is obviously different for everyone - some people have higher CPMs but their audience hates mid-roll ads, while some with lower CPMs compensate with more mid-roll ads.
For me personally, if I can get this channel to 10k views/day, based on my current CPM and number of monetized views, I'd literally be able to live off of ad revenue alone. I'm already 10% there, so I hope I hit that goal some time in 2021.
