Maybe it's not so much the topic or subject but marketing.
This.
What it takes to gain followers on YouTube is promotion, promotion, promotion. No matter what your subject is, it won't gain following if people can't find it, and people can't find it if it's not promoted.
And then, the videos themselves have to be pleasant to watch. Are your videos well made? Polished? Nice backdrop, well edited? If they look too obviously amateur, that will drive viewers away even if they're otherwise interested in the subject.
Finally, the subject has to be something that attracts people, and it has to be distinguishable from all the gazillion other videos on YouTube. There are already lots and lots and LOTS of cooking videos. There are already lots and lots and LOTS of sewing videos. Never having heard of ASMR before, I had to look it up, but apparently there are lots and lots of those, too.
What it takes to gain following is doing something no one else is doing. Or doing something in a very new and different way.
Your Aquarian MC backs that up. For you in particular to gain recognition, on YouTube or otherwise, you NEED to be sending out a new and different message. Just the same old same old won't cut it.
Your chart doesn't specify what your message should be, but it does tell us that it needs to be authentic. Modern MC ruler Uranus in Capricorn: Capricorn demands authenticity. So does Saturn, the traditional ruler of your MC. If you choose a subject just because you think it's what others want, but it's not authentically you, it won't work.
But given that you have
you could try a
sex video chat show where you go over Dr. Ruth's shows & re-invent it for the new generation. People have a lot of questions about sex & you could tackle one topic per week or per day depending on how much time you want to give it.
Good Luck!
I see lots of indicators in your chart that sexuality is, or could be, very important to you. If my interpretation (and blackbery's) is correct about that, then that might be your authentic message. However, YouTube demonetizes all videos that deal with sexuality in any way, shape or form. If you're looking to make money, sexuality-related videos on YouTube won't do it. They won't even pay for themselves. You'll need other sources of funding.
There are creators who post non-explicit informative videos about sexuality-related topics, but they all have outside funding. They may use the YouTube video to help drive traffic to a Patreon page or something like that, but they're not getting money from YouTube.
