The very concept of 'popularity' is completely foreign to my experience. I don't think there was a thing such as a popular kid when I was at school or high school.
I personally enjoyed a lot going to school because I could spend time with my friends. I have never witnessed any violence apart from fights form time to time between two malse wanting to show who the strongest was. I was not in a privileged school.
In every school I'd say like people hung out with like people. So the "popularity" would be limited to that in-group. Most of people who PG would call "nerds" had a clique of their own as far as I could tell.
Some people might have been broadly disliked though.
The scenarios described in the GP link is a very late 70s-80s (Gen X) thing. 90s and early 00s high-schoolers had somewhat different experiences, but they know the trope since that's what was in movies. Schools today have a different concept of a "pecking order" - it's not that nerds aren't at the bottom anymore, it's that the whole concept changed.
This is just judging from my own experience, and my kids have a very different set of circumstances then I did.
