I think you're overestimating how hard CS is compared to other fields (hint: it's not harder). They teach calculus in high school. And calculus-based physics. They have autoshop and woodshop which is honestly very similar to the kind of CS I would imagine high school students learning (understanding systems, debugging, building them, learning which pieces fit where and how to make them do what you want, following tutorials and being able to figure things out when they go wrong)

what percentage of high school students actually learn calculus and physics (and get at least OK grades)?

Only 26% of high school seniors are considered "Proficient" at math, which I can assure you is a MUCH lower bar than knowing calculus.
