Youtube Channel Monetization

Hello, I own a channel with a video in a niche that got insanely popular and got 2 Million views in some years. Two years ago I uploaded a random video similar to that in the same niche with the same account and now it has 1,3 Million views. Both videos are compilations and are not mine. I have monetization disabled on the channel i dont know why, and 5000 random subscribers maybe for the videos.

Is there any way I can use my channel?
