Your not using any searchable keywords meaning no one is searching for your videos outside of searching for your titles.
Your thumbnails need work, a thumbnail that doesn't look inviting won't get clicked, meaning you won't get views.
Your second most recent video is age restricted because it's about cooking with a controlled substannce. While cannabis is being legalised in some countries, it's still illegal in many countries meaning that you're teaching how to use a controlled substance which means YouTube will restrict and suppress it from being shared out.
But overall I think you'd benefit from learning some extra photography, lighting tips, and how to create more clickable thumbnails. Thumbnails are very tricky to learn how to do when you've had no experience in art or design, but are the most important element outside of SEO in getting a click.
Once you start using keywords, learn to make better descriptions (DON'T use just hashtags as a description which is what you're doing) and have some more appealing thumbnails, your views should raise a bit more.
