I took AP Stats in high school. I took a calculus based probability course at MIT. The former was extremely important to me and I learned a ton. The latter was interesting, but mostly unnecessary. A z-score lookup table is more than enough to teach the concept of a normal cdf without actually being able to derive it yourself. As a professional data scientist I've never needed to use calculus unless you consider graphical reasoning on distribution diagrams to be calculus.
