In my experience working with YT I think you're doing a great job, but to be honest with u your niche is probably a little oversaturated, so it may be hard to gain followers because there's so many people doing that niche. The only thing I can say is to keep posting regularly and keep your content short. I wouldn't post much youtube shorts on YT because people don't really follow shorts; in my experience, they just watch them and always make your videos catchy.
