This is an insightful comment. My first-order take had been that the lucrative jobs that the video advertises are plentiful only if the "math person" is also proficient at some type of computing. Reason is, I've known a lot of mathematically talented people who are not able to compete for these kind of jobs because they have no sense of how to compute with their abstractions. But I think your idea captures the problem with the video better than the simplistic "lack of computing expertise" does. The budding "math person" that the video targets could do quite well at, say, a biological or finance application, even without being computer-savvy, just by acquiring expertise in these areas.
