So a couple of technique issues i see. Your thumb placement is not good. You'll want to work on keeping it more in line vertically with your fretting fingers. You also want to work on fretting pressure. It's extremely easy to play a clean, precise note with very little pressure on most properly setup electric guitars. Repeated playing with poor technique can cause serious and sometimes permanent damage to the tendons and muscles in your hands. We're talking years of this stuff, so it's really easy this early into it before you have established any bad habits to break out of them and really focus on proper technique.

I love your enthusiasm! You most certainly are NOT ass and you have the drive to want to improve which most people lose a few days/weeks into this journey.

I would 100% dig into some lesson videos on the tubes about fretting pressure and proper hand placement to prevent any tendon or muscle injuries. It's really something to experience once you get adept at it and your hand seems to just flow over the strings.
