It's probably way easier to decide on a subject you want to learn more about, and find the most approachable textbook / lecture notes on e.g. StackExchange. It doesn't make sense to choose courses (or even subjects to learn) based on whether video lectures are available.

I don't maintain a collection of these, but I can probably recommend

* Stephen Abbott, Understanding Analysis, for mathematical analysis and a little bit of real analysis

* David Williams, Probability with Martingales, for advanced probability

* Dym and McKean, Fourier Series and Integrals

Alternatively if you have a more cursory interest, you can probably check out Metacademy [1] which provides roadmaps to learning a variety of math (and ML) concepts.

Although I am a bit interested in number theory, linear algebra and a bit of calculus and its applications, I still haven't fixed my mind on specific fields. Now from time to time I watch videos on popular math YouTube channels so I can see what I like most.
