This is typical for many people. You love pre-college math because you have intuitive understanding, while college-level maths offer a new level of abstraction that you may not feel familiar with from the get-go.
It's perfectly okay not to learn linear algebra, by the way, especially when you don't find any incentive to do so. Otherwise, you'll find linear algebra to be one of the most intuitive tools to model so many problems.
If you do want to learn linear algebra or any other higher math, I'd strongly recommend you focus on understanding concepts intuitively first, to the point that you find many exercises in a text book straight forward. Watching 3blue1brown is a good start, but do move forward with deeper treatment. The book I find very usual is David Lay's Linear Algebra and Its Applications: https://www.amazon.com/Linear-Algebra-Its-Applications-5th/d.... Lay sets up a really intuitive geometric framework to explain the intuition of linear transformation with sufficient rigor.
No. I took only a few courses on probability and mathematical stats. The books are A First Course in Probability and some some textbook on Mathematical Stats. The courses were probably not advanced enough, as I found them reasonably straightforward. I struggled a bit on what exactly is a random variable, but once that was internalized, everything else followed. I heard that advanced courses like random processes were really hard, but I'm not at that level.

Got any similar recommendations for college-level probability/stats stuff?
