Hey Levi,
Great video - I'm a huge fan of Sufi Dhol as well. I have this Gunga Sain recording on my phone that I ripped from a video years ago, and to this day, I still listen to it over and over.
I don't think there are any resources out there that will break it down for you but you may be able to reach out to some people who are willing to share some of their knowledge.
Not sure if this will help, but try reaching out to the following people (I just came across these profiles on instagram):
www.instagram.com/dholbros
www.instagram.com/ustadabidsain
Also, there's a lot of good content on the following account (more general stuff):

Hope you find what you're looking for!
