How to put Adsense Text on Youtube Video Page?

I have seen Youtube users with entrenched Adsense text ads on the right side of their video playing pages on YouTube. How do I do that for my own Youtube video page? I tried to figure this out for awhile and still I can't figure it out. I want to make some money with Adsense on Youtube. Any Youtube gurus know the answer? Thanks.

Best regard,

Matt
Answers:    You have to be a YouTube "Partner", which means you either hold to be a film
creator/director, a broadcaster, an advertiser, someone with a special project,
or a person of special significance (like Her Majesty Queen Rania Al Abdullah).

But that's not adequate to become a YT partner. YouTube has even more criteria:
-- You create your own "original" videos
-- You own all the appropriate copyrights
-- The content is 100% yours (no income splitting/sharing if money is involved)
-- You upload video on a regular basis
-- Your videos are viewed by thousands
-- You're contained by an English-speaking country.

Only after you've finally been approved by the YouTube administrators/directors
will they give you the all special tools and codes required enable you to have:
-- a customized special logo or "banner"
-- different capabilities of "scripting fonts"
-- your channel-page video on "autoplay"
-- "high-definition" quality to your video
-- a "More From" section which automatically opens up above "Related Videos".

If you want to know more, go to the top right-hand corner of any YouTube page,
click "help" and afterwards type in the searchbox the word "partner".
