Keep training. It takes a long time to even scratch the surface with grappling.
On Youtube you can find videos made by Rorion Gracie, Damian Maia, and Stephan Kesting easily. You can also find instructionals by a plethora of other legitimate Brazilian Jiu-Jitsu black belts. The submissions 101 guy has no black belt. As far as I am aware, he is a white belt in BJJ with a black belt in JJJ and a purple shirt (that many say he bought) from 10th planet. There are MUCH better easy to find instructionals out there than submissions 101.
