The odds of a sustained fight have to be a .0000000001 to one
I'm not sure how that helps us here.
The likelihood of
ever needing to fire a weapon in self defense is exceeding low. However, the question of how many rounds will be enough has to be evaluated on the basis of the assumption that shooting
will be required.
On that point, reflect upon the following:

Even the best shooters miss occasionally.
And attackers often require more than one shot to be stopped.
And sometimes attackers work in teams.
A member recently posted some statistics about sixty three actual SD encounters. See
this.
The mean number of shots per encounter was 4.7 rounds. Encounters involving no shots fired were not included in the calculation. No one fired 4.7 rounds. The frequency distribution was not provided. In three quarters of the incidents, more than one attacker were involved.
We can conclude that for some of the encounters, five rounds or less were sufficient--that's somewhere between one and five, inclusive. We can conclude that for some, more than five were most probably required. We do not know the maximum. We do not know what would was required for the sixty fourth or subsequent data points. And if we did, we would not be able to conclude very much about the maximum based on such a small data sample.
In point of fact, we cannot say how many shots are "enough" until the situation arises, and then, the answer only applies to that incident.
We can only make an informed judgment. I often carry five, but I prefer more.
This recent episode of
The Best Defense is relevant and is worth watching.
