Statistics without calculus relies pretty heavily on memorization to get the right answers. I'm remembering my AP Statistics class (high school) where most of the time students got lower grades because they looked up numbers in a table wrong, or used the wrong table. Never mind when you start using regression models and need to start understanding axioms of the models you are using like homoscedasticity. There's some intuition there, but generally speaking, calculus is where most people "mature" into mathematics. I would argue that most people (NOT engineers/doctors/etc.) don't really get the point of math until around calculus where it starts to really open up for them. While statistics would certainly be useful, and is a must for modern day ever-connected society, it would just be another math subject that needs to be memorized like trigonometry. Some people mature in math a lot younger, but it entirely depends on the quality of their math teachers when growing up (and the curriculum/testing focus in which they are subjected to).
