Welcome to Freedom! What kind of gaming content do you plan to make? I'd say as a pointer, try to focus more on your content and not as much on gaining the subs and numbers. As long as you keep everything more casual and more as a hobby, it stays fun and the rest will follow suit!
I agree. Active subs are amazing, but are just so hard to come by. If every one of my subs were active, everything would be so much easier. It's all part of the process though
You just can't let it get you down. Chances are they'd be a dead sub to you anyways, so it's probably a good thing. It sucks, but you just gotta get back on the horse and make some good content!
