Yeah. YouTube’s algorithm strongly pushes that you recently watched, along with a sprinkle of rage bait. If the dude is getting videos of people dancing, they watched videos of people dancing. For generally innocuous stuff, it tries to get you on binges.
It’s YouTube’s rage bait that is extremely annoying as even one video can take over your entire recommended.
I watched ONE single half of a video of that drunken reviewer who’s actually just a massive bigot and pushes a lot of misogyny in particular, and it took like 14 months of blocking and “do not recommend” for the rage bait to stop being the primary piece of recommended, though I still get the odd “here’s why women are trash and belong in the kitchen, not working” video.
