and you don't always earn more than Adsense, you can earn less with a Network or you can earn more.
You earn revenue through the advertisements displayed in and around your videos, the revenue goes to your Adsense account which you associated with monetization. although you will have to reach $100 or more in payable balances to be able to receive your earnings by Check or Bank transfer.
A lot of people on here don't advise monetizing until you join a Network but I think it's nonsense not everyone gets disabled from adsense. (I never did for 3 years)
