Ok, lets say you are in an auditorium with people randomly dispersed and the roof collapses. However, three people near the door are not killed by falling debris and live to reproduce. Nothing about there genetics contributed to their survival, it was purely chance. That is a bottlenecking effect.
That's true, but that is not a population bottleneck.
If there was only enough food to feed 1/4 of the people in the auditorium, only the strongest and smartest will survive. That would be a bottleneck.
