As for me, it used to be 50/50 back when I studied. However, ever since I've entered the workforce I mostly stopped watching videos.

I need to constantly learn new things, tackle new problems and optimize stuff. I usually go for the highest difficulties too. In theory, my job provides these tasks for me, however, I get a lot of satisfaction from trying and failing things over and over until I've figured them out myself. I can't usually do this professionally, as most problems have already been solved and I'm just learning how others did it. The same as playing with a guide or watching a video on a game. It just doesn't scratch the itch.
