this is a distro called arch and its really complicated tbh, but you can totally get a "just works" distro like pop_os or nobara and it'll be really easy :)

The goal of using a window manager is basically making your own custom desktop. The majority of apps are configured through text files. If you want to try Linux, you can pick a beginner friendly distro like Fedora which will give you a desktop environment. These are desktops with the batteries included and are fully customised through GUI settings menus.

Fedora KDE is a great option if you want to try making a very custom looking system without having to worry about installing a ton of different tools and editing config files.

Just so you know, OP took basically one of the most complicated routes, learning all this stuff is entirely optional when it comes to learning Linux
