It is said that only 6% of YouTube channels are monetized.
I dunno. Based on my own viewing experience with most YTs, there’s an awful lot of ‘something’ going on. I rarely see anything anymore that’s a ‘straight-to-the-point’ video with no ad promos. Regardless of how you cut it, sponsored by ad revenue is a form of monetization and those agreements aren’t always clear about what ‘tit’ is for ‘tat.’
And then there are the vlogs that pretty shamelessly hawk their wares for anything from subscriptions, donations, visits to merchandise links, investments and anything else that could derive funding.
