There are good stats classes and bad stats classes, just like there are good calculus classes and bad ones. When I was a student, we spend a full term learning integration techniques, with almost no class time devoted do learning what an integral actually is. The fundamental theorem of algebra was glossed over in a way that makes me think the lecturer didn't really understand it. Differential equations was a catalog of recipes, with almost no modeling and certainly no qualitative analysis. I got an A+ in the course but learned almost nothing from it.

Fortunately, I had a great professor in Calc III who more than made up for this.
