In regards to Bayes Theorem in the XKCD comic being used in the 'real world'... I haven't ever really learned about the theorem except in passing through some

In regards to Bayes Theorem in the XKCD comic being used in the 'real world'... I haven't ever really learned about the theorem except in passing through some articles and a brief mention in highschool once. Even so, I still ended up basically using Bayes Theorem to successfully do something IRL. What was it? Hunting ghosts in a game called phasmophobia. Some friends and myself were playing it on discord and were having a hard time figuring out which ghost it was we were supposed to be hunting. That is, until I started trying to figure out the negatives before figuring out the positives. The others were curious as to what I was doing, as it seemed to be working finally, and so I told them; "I'm fairly certain this game is using a rudimentary form of Bayes theorem, which is how we are finally getting these correct." And correct we were, time and time again; despite never having gotten all the respective 'positive' clues. So, in regards to the comic... I understood it well enough?
