Regarding your example, I think what Mills is saying is probably a fair point—or rather, it’s probably a gesture towards a fair point, muddied by rhetorical constraints and perhaps misunderstanding of probability. It is very difficult to actually get good numbers to predict things outside of our past experience, and so probability as used by humans to decide policy is likely to have significant biases.
