Caveat: I am not a
lawyer youtuber.
Help with what? There's nothing stopping you making more videos if you want to make more videos. Be prepared to (a) make many videos, (b) have hardly anyone watching them for ages and (c) fail.
If you somehow succeed in producing one extremely popular video early on, it will probably result in your channel failing to do much. The "one hit wonder" problem of music exists just as much with Youtube. Whatever you make afterwards will generally be perceived as either being not enough like the one hit or too much like the one hit or not as good as the one hit. Although whatever you do, you will probably fail. Youtube is about as saturated a market as you can possibly get. The best you can
reasonably hope for is for it to be a hobby that makes you some pocket money in exhange for a disproportionate amount of work, so it had better be something you would be doing as a hobby anyway. Churning out videos is work, but if you don't enjoy doing it you're unlikely to find many people who enjoy watching that.
This chap is quite successful on Youtube (and now off it as well) and explains it better:

The subtitle he gives the miniseries also says a lot: "Based on 15 years making things that are only sometimes popular on the internet". That's how it works - you need to make many things and not expect all of them to be popular. Or even most of them. Also, if you're not making a political channel, avoid politics at all cost. He made a political video after Trump was elected and it cost him a lot. He very quickly deleted it and makes no reference to it, hoping that everyone will forget it ever existed, and never refers to his political position on anything. If you make videos on something apolitical, you will attract viewers with different political views. If you then show some political position, you will alienate some of your viewers, whatever your political position is.
It's like many things - there's a lot of focus on the handful who make it big and none at all on the multitudes who don't. Hope to succeed. Expect to fail and plan accordingly.
