Sure, not ALL accountants are athletes, but some are athletic, and can run a mile near 4 minutes, while others can bench 300 pounds. Other accountants have been known to be great basketball players and swimmers, etc, etc, etc.
But, one doesn't need to be an athlete to be a good accountant. Just as one doesn't need to be an athlete to drive a car fast. Sure, many race car drivers are very athletic. They have a lot of spare time between races to work out, but one does not need to be athletic to be a good race car driver.
That is why we can say that race car driving is not an athletic event.
