But that's like saying everybody who learns to program needs to know electrical engineering so they understand how CPUs work. Just as most programmers don't need that to be good programmers, knowing useful statistics doesn't mean deriving things from first principles but rather knowing what statistical test to apply to analyze data and how to interpret the results. This doesn't need calculus.
