there is a difference between proficiency with shooting games, and with self defense. I never have said that training is not a good thing, but despite 'confirmation bias', the vast majority of self defense shootings are engaged in with zero professional training.
To my knowledge there isn’t a centralized database of civilian uses of a firearm for defense. Knowing the background of each shooter in every shooting isn’t something that’s easy. Most of what we have are news reports that are limited in details. That said I am willing to believe the percentage of people that both own a firearm and receive additional training is relatively small, so I don’t disagree with your premise, nor did I in my comment. My point is just because that is the case doesn’t mean training may not have been beneficial in those instances. Additionally, just because someone else survived a defensive shooting without additional training doesn’t mean I personally won’t get additional training. Decision making varies a lot person to person, so someone choosing differently than myself isn’t unexpected.
