Unless the author is an accountant or otherwise close to the field (e.g., talkative friend is an accountant), this is a weak statement. I doubt people not in tech know that people in tech write articles arguing about "born programmers" and "10X" programmers. Such talk is internal to our field.
Most people do know a lot about sports, because sports is very interesting for most people. Accounting and programming, on the other hand, are opaque and boring-sounding to most people. When the author talks about accounting, then (again, unless the author is an accountant or close to the field - I see no mention of either) that could be talk about a stereotype of the field of accounting, not actual accounting.
Just for fun, a non-stereotypical super-accountant is Lewis Litt from the TV show Suits. He's clearly a rockstar accountant in that show, capable of achieving things 100 average accountants can't. Is he a realistic character? I don't know, just like I don't know if the "all accountants are about the same" stereotype is true.
All of this doesn't necessarily undermine the entire point of the article, of course - maybe accounting is not a good example, but some other field could be.
