If you do better with an honest-to-goodness course, I'd recommend Outlier, as they have for-credit courses in introductory stats, calculus 1, college algebra, and pre-calc, depending on your previous math level: https://www.outlier.org/
Many people, however, have found more success starting with a course like fast.ai, which does not assume much mathematical maturity, before later diving into mathematics. But, I'd still recommend learning the math, even if you ultimately don't fall in love with the field of statistical learning. I've met many people who took a "higher" math course for the first time as adults and discovered that they loved the subject so much more than they did in high school.
