Its hilarious because we are not guaranteed 12 games. Do we get at least 12 games the vast majority of the time, yes, but there are obviously cases like 2017 or 2020 where we don't get 12 games, so it's not guaranteed.
In your argument about 6 wins, you are arguing based on the minority of cases. Under normal conditions, 6 wins means we went to a bowl and lost, ending up 6-7 so a losing season overall. Is it possible that Tech gets to 6-6 and either receives no bowl invite or declines a bowl, thus not resulting in a winning or losing season, yes, but there is a very small probability of that happening.
So again, its hilarious because in one argument you are accounting for fringe cases and the other you are ignoring them completely.
