Hello all!

I'm kinda finally done with windows, but I have a lot of small, maybe dumb questions.

I guess my first question is whether Linux knowledge in general is interchangeable between distros?

And second, more importantly, what are the good resources for learning basic things? Like if I want to play games I bought on steam, how can I expect that process to be different? If I want to manage files and folders and extensions and such how does that differ if at all from Windows. I'm coming from specifically windows, but I assume for people coming from Mac OS as well what are the do's and don'ts that you wouldn't necessarily think of when switching?

Are there any particularly well made and comprehensive instructional/introductory podcasts/YouTube video series/what have you that you would point me towards?
