Absolutely. Personal experience FWIW -- 30 years ago, different sport (wrestling), different country, different culture, very low amateurish level, but typically the same attitude. First time I got a moderately serious injury (torn acromial ligament, couldn't move the arm for 6 months), I basically got yelled at by the coach saying either I continue to came to training and work with the other hand, or I split off. So the next time (I landed almost vertically on the top of my head instead of flatly on the back -- now he was afraid, but I was so proud of myself, didn't even want to interrupt the exercise.

Fast forward 30 years. I realise now that in some sports, people who didn't make it "to the top", are sometimes left with what seems like small stuff when you're 16 -- damaged teeth, torn ligaments, broken ribs -- but which age much, much worse than the rest of the body.
