YouTube requires original content that you own or creative commons video content. This content can be uploaded through YouTube uploader. The content needs to have around 10k views in order to be monetized for entire account. So once monetization is enabled, your video views and the ad clicks will earn you adsense money. This adsense money will be shown in adsense account.
Follow these steps:
1. If you are yet to create adsense account, I suggest opening YouTube account first instead.
2. Start posting your videos on the channel. Make sure channel has attractive names.
3. Don't copy video content from other channels, that' eventually gets your YouTube account banned.
4. After you make youtube channel, upload the videos. And make sure you get total 10K views for entire channel. This way you can be eligible for the monetization.
5. After monetization requirement reached, youtube sends invite for adsense monetization.
6. Sign for adsense account and then connect the account to youtube after approval.
7. If your youtube earnings cross 100$ a month, you'd be able to get paid through NEFT in your bank account.
Hope this helps start with the YouTube and monetization.
