There is a sense in which models cannot be right, because they aren't reality, but models. Maths can only refer to reality. It is a form of speech about it, and like all speech, can only partially accurately refer to reality and must, at some point, diverge from the reality that is being described.

Just as our understanding can only be partial, even though we can reach 12 decimals of accuracy, in fundamental ways we cannot precisely know anything accurately, as Nima points out as the problem we have precisely characterizing reality.

Thanks!
