Package manager is your friend. Learn "whom is whom" in Linux (alsa = your sound "driver", for instance) and how to fully customize your Linux installation are what I'd call as "The Holy Trinity" of Linux. Know those, and you can call yourself a penguin.
The distro choice just depends on how much you wanna "learn" about Linux; if you wanna learn a little bit about it, and have a rock-solid distro, with a small RAM usage, I'd recommend Debian stable or testing, with the Mate desktop!
I'd suggest starting with a distro that very user friendly. Pop OS was the distro that made me ditch windows completely. I could also recommend Manjaro, it's almost as user friendly but it has AUR which basically let's you install stuff from github directly if a package isn't available (For example xpadneo is basically a requirement if you use a controller with Bluetooth and it's only in github). I haven't had to open a terminal with Manjaro since the first install.
You can find answer to most of the questions in google. And there are always people who are willing to help in the internets.
@qooqie Start with the most user friendly distro TROMjaro. Even my mom computer retarded have no problems of using it.
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
