I spent 400 on an AI course and learned almost nothing applicable, so what actually works for non-technical people?

I am 34, work in HR, and decided six months ago that I needed to properly understand AI to stay relevant. I bought a well-reviewed online course. It was 22 hours long, taught by someone with a PhD, and by hour three it was deep into Python syntax and gradient descent. I finished it. I cannot apply a single thing from it to my actual job.

What I needed was not how to build an AI model. It was how to think about where AI fits in business processes, how to evaluate AI tools, how to have informed conversations with technical colleagues, and how to use the tools that already exist more effectively.

Does that course exist? What did actually work for people who came from a non-technical background and now feel genuinely competent talking about and working with AI? I do not want another mistake.
