I found this course very helpful if you're interested in a bit of math (but all very well explained): https://diffusion.csail.mit.edu/

It is short, with good lecture notes and has hands on examples that are very approachable (with solutions available if you get stuck).

I found it to be the best resource to understand the material. That's certainly a good reference to delve deeper into the intuitions given by OP (it's about 5 hours of lectures, plus exercises).
