Tiktok niche

hello, so i started a new tiktok account with a goal to get into the program. my niche is 3d animated content (animated 3d caracters and sometimes i use the viral skeleton catacter) i try to go more into educational and health content (like some what if and stuff) because i heard it pays more. I'm still stuck between 600-1000 views because my "wacthed full video" rate is less than 10% and my average watch time is around 15 seconds. what id like to know is what should my analytics look like in order to have a viral video (60+ seconds) ? And does an educational niche pays well or because I'm using a viral caracter it'll lower my RPM?

note: i started a month ago with storytelling niche, i used to do ai photos and just add some elevenlabs script and captions, but i realised it's too saturated so i switched to educational niche 2 weeks after and started generating videos and since i did that I've been getting very good interaction rate and 95% of viewers are from the usa
