Is this some kind of joke

Give that the most popular YouTube channel is one of these annoying games reviewers I'd have to say that unfortunately the silliness seems to work out quite well. There isn't much chance of you making much money from this - unless you're very charismatic/funny I really doubt a 'Dad' is going to appeal to the people who watch these things given that three are already thousands of kids out there creating these videos.
Woodysgamertag filled that exact type of 'youtuber' of being a sensible dad who had fun playing games, he was successful enough to do it full time and make serious money.

Without stating the obvious you won't have the time in all likelihood. As a stay at home dad you will have to be doing things when they are asleep or recovering your energy so you can do the stay at home dad stuff happily and properly. And that's speaking as someone who had the same idea as you when I was stay at home dad for two of my children. After a time I put them with a childminder so I could concentrate on work because trying to do both leaves you doing a disservice to both imo.
