First u should have 200k views then they them self will tell u to go to ur bank account and have the money

You have to reach 5k hours view time and 1k sub. After that monetization option will be available on ur setting. Then go ahead and monetize ur channel then u will receive the money

I don't know but there are YouTube videos on that. You better check them about. Aside from how you get money, they also teach you how to open an account, how to gain subscribers, how to fit in the algorithm, how to monitize (avoid copyright) your videos and how much you earn based on your video's content. Think those will help you out a lot
