Because numbers don't tell the whole story. I don't mind stats but some people act as if they are conclusive. Predictors yes, conclusive in a future outcome? No. Numbers will never account for heart, the will to win. There's no % for resiliency. The numbers said statistically I would be dead by 25 due to gun violence and the life I was living. But the numbers couldn't account for ones will to straighten up and seek an education. Just sayin. I'm done.
I get your point, and you make some valid ones, but your point is about exceptions, not rules.
You cannot extrapolate from an exception to make a rule.
Taken at the lowest levels, things get very difficult to predict. The way one human will react, the outcome of one football game, the behavior of one molecule are all good examples. However, if you take millions of molecules, demographic slices of humanity, or seasons of football for whole conferences you can in fact see patterns and general predictors of specific behavior and outcomes.
It is to your peril if you try to say that every game, or every human, or every molecule will behave exactly as the general population. That is my point. Exceptions and general rules are things to be viewed separately. You must understand the general rules to appreciate and celebrate the exceptions.
Congratulations, by the way, on whatever it is that you overcame and I wish you continued success. Without the exceptions, like yourself, life would get incredibly boring.
