Adsense on my youtube videos?

I uploaded recently some videos on youtube and I see some got adsense on the player and in the right side.
However I dont have associated my youtube account with adsense.
Are those ads from youtube or what happened and if so how can I disable them.

 

They're ads from youtube. If you're videos become very popular, you can become a YouTube Partner which allows you to gain revenue when these ads are clicked. You can't remove them, however.

 

if your video(s) become very popular you will be contacted but up until then, you get $0.

 

I've contacted YouTube to ask them but they said me, that this is program only for most popular publishers on YouTube.

 

you can only earn money from it once you become a youtube partner. To become a youtube partner you need A LOT of subs

 

how popular do they need to become and if so is it worth putting time into creating a few good videos.

 

i thought i can put adsense code on my youtube videos. I hope so.

 

It is still a secret to me. I guess few millions of page loads will make you youtube partner.
