You can definitely grow. I'm not showing my face and I've been growing decently for my own standards. Maybe you'd like to get to tens or hundreds of thousands of subs and views. I can't tell you how to get there obviously, but based on the YT channels I follow, it seems achievable.
The biggest bottle-neck, in my experience, is your upload frequency. Whenever I manage to dump a lot of new videos in a short time frame, I get a temporary boost by the algorithm. Lately, I've fallen off a bit, less videos, and my newest videos aren't getting recommended as much as the videos I did 2-3 months ago.
Anecdotal evidence, I know, but that seems to be a pattern that repeats itself in my case, over and over again.
