The nerd/jock dichotomy is at best loosely pointing at some genuine clusters of interests and predilections that exist among people in the world, and is more often taking a set of tropes from 80s Hollywood movies about high school and using them to try to explain how real people in the world are today, which is stupid.
(Who wrote all those 80s movies? Bookworms! Who acted in them? Theater kids!)
Life imitates art. The dichotomy is stronger than ever especially with the rise of incel rhetoric in mainstream circles.
The jocks at my school (Championship Winners) were also simultaneously the smartest kids at it. Most went to Ivy Leagues on academic scholarships. I know a few of them were the first engineers on several well known unicorns.
