Given all the major tech companies aggressively fuzz everything maybe, just maybe, you're missing the additional possibility: fuzzing is still random and extensive fuzzing does not mean you will encounter the same code paths as anyone else.
You need to understand "do fuzzing" is not a magic trick to find all bugs in software.
Similarly: definitionally you will only ever see the bugs that are not found prior to shipping - any bugs that are found prior to software shipping will have been fixed.
