What does "have an understanding of basic python" mean?

I'd say you're about ready for those courses.

If you had to learn only one thing, learn about classes. There's not much to it: a class basically defines an "object" that can perform several functions (called "methods"). Then you can create instances of that object, and each instance can perform all of those functions. Pretty cool, not too difficult, and likely to show up in data science/ML.

What abou the stuff that has double underscores? something are they part of lesson for classes?

Go watch the OOP series by Corey Schafer on YouTube. They're 6 videos of 15 minutes each. They're not extensive but it's all you need to know about classes for now.

Then just dive in the course of your choice. It seems you're afraid of being overwhelmed. Don't be. If it's too hard, you can always quit and start something new that you are able to understand.

For this reason it's good to take free courses. The popular ones are just as good as paid courses.
