Don't underestimate what a good Thumbnail and the YouTube algorithm sometimes does.
I've been getting this one stupid video for years in my recommendations the second I dare watching any video about C4D / Blender / After Effects. I've talked to collegues and they all know this video as well and have been getting the recommendation for years.
Talking about this one specifically:
That video has 19 Million (!!!) views. It's not even a tutorial, it's literally just a 1,5h long timelapse. I think it's entirely worthless.
But it has a good title, and a good thumbnail. Sometimes you just need to get lucky with your videos and they just straight up snowball from there.
