[Question] How this guy rank his video?

I do a searh on youtube and the result show a video on top 1 with NO VIEWS, NO LIKE
When I click on his channel, i found that he was uploading tons of video, with different niches
so, my question is, how can he rank his video on page 1?
Thank you!

Mass upload > Channel authority.
You are blind?

How to build channel authority?
Other then adding subscribers
