CPM's vary wildly. I've seen Real Estate/Crypto/Financial Channels pull CPM's that are consistently in the $40's. I've seen gaming channels and Shorts channels pull consistent .25 CPM's. Long story short; unless you are pulling between 25,000 and 1,000,000 views per month you don't even need to worry about it, you aren't going to see a check any time soon and when you do it isn't going to be for much. The real money is in the business behind the channel.
