Omg...I actually can't believe this.
First of all, YouTube DONT video you. YOU video yourself, hence the "YOU" in YouTube...
Here's some advice:
• Buy a camera. Video yourself, upload to your conputter, and then you can either get an editing software on your computer or upload it straight to YouTube (assuming you have an account)
• If it's games you want to video, buy a decent recording software (like DxTory) and a Microphone. Set it up and start recording your games. Then you can either edit your recordings with a video editing software, save and then upload to YouTube.
It's as simple as that, only the editing really takes up a lot of your time. Also, please learn how the internet works, that may get you somewhere in life. :)
