Do you need to exhaust mental energy to get good at this game?

I play games to help me relax and decompress since my work requires me to work with numbers and excell sheets. I've been watching tutorials in how to make automation work? But I just don't get it. The NOT gates and other stuff just won't stick in my head. I guess this game is just not for me unless I devote mental energy to it which is the reverse of why I play games. Did anyone else encounter this and found a way to break through?
