This was probably meant as a typical math/Bayesian question, so why no responses related to math?

There are over 200,000,000 streetfighters; in contrast to a pool of maybe 40,000 US citizens seriously considering a career as a SEAL (of course not an ordinary sample by any means), etc.

Also, there are considerations of what characteristics any outliers would possess, e.g. maybe good grapplers with fantastic (read, out of this world, never seen before) head butting abilities would just win, no matter what category they belong to, but they'd be more likely to be found in the streetfighter category just by the math alone.

Ah, now you are all better poker players, how does that feel?
