Are most gym rats insecure?

I'm asking this because I met a former track & field athlete/long jumper who did a few years of vale todo in the gym a few weeks ago

the part that intrigued me about him is how fast & high he used to jump
(he showed me old tapes of him in his prime) he was very lean & cut & he was pretty technical with his vale todohe showed me a few of his 2nd place medals but what intrigued also was how quiet & humble he was... he told me he would never boast about his triumphs & abilities now when you compare this guy to the gym rats who act like animals & most likely wouldn't be scouted for the Olympic trials then you see someone who is truly secure in themselves I'm shocked that someone with that much ability would not want to showcase their skills
