Exactly this. Athletes are an outlier when it comes to BMI.

Furthermore, I reckon the majority of the people discussing BMI, as in these comments, would tend to be outliers, too, based solely on the fact they care/understand.

The majority of the population has no fucking clue, and can’t even read nutrition labels. And I am not blaming them. This stuff should be taught in school—basic nutrition education.

And even most athletes I personally know fall under what's considered a healthy BMI (< 25). Some sports require a body composition that pushes the boundary of it but as a general proxy of the health of millions in a population it's a pretty good one.
