Realistically you don't have to if you're not constantly tinkering, but if you're changing a lot of low-level stuff without knowing what you're doing, you have the ability to break things. If you don't know how to fix them, then it's easier to just reformat. Basically it's a skill issue lol.
I've broke things often and had to reinstall a lot because I didn't know what I was doing. Still kinda don't know, but do y'all recommend anyways to learn the knowledge?
Like I could probably read through man pages but I want something that shows how everything builds on each other to fill any gaps I'm missing
The Arch Linux Wiki is an incredible resource, even if you're running another distro. Most of it is pretty universal (other than specific commands like the package manager), and it explains how everything functions and fits together. If I'm troubleshooting, it's always my first stop.
That and the Gentoo handbook are two of the best resources for learning things about how Linux works
Just keep breaking stuff! It means your learning and trying new things, for the most part. Eventually you'll just break stuff less and less or know what to look for when something breaks. On that note do try to struggle with something a little bit before rolling back or reinstalling.
I would recommend reading the manuals yes. Their are many manuals and not all are equal. The man pages can feel a bit strange as they list everything the software can do. To learn I found the archwiki to be better. (Also info manuals but many people are weirded out by the controls used to read these.)
Also don't blame yourself for reinstalling if you mess up. It's normal especially if you need the computer to actually work in a timely fashion
Getting comfortable with manpages and regex will get you pretty far, this is a really great resource for beginners (available for free as .pdf):

Depends on what you're breaking I guess. If it's DE stuff, kernel stuff, etc. Usually I just find a good YouTube tutorial if I want to learn something new and don't know what I'm doing.
Yep tinkering with the system is probably the main issue (for that NixOS is awesome btw.). But even when you're not constantly tinkering. System-State accumulates over time, bugs are also apparent in (upgrading of) distros, and the maintainers of a distro cannot realistically handle every upgrade time-point x -> y, so stuff will likely break after some time.
But even when I have fixed all the issues in my previous at some time broken distros, at some point it just feels good to have a freshly installed system without all that dirty accumulated state (NixOS + impermanence and you'll have that every reboot :P, see also this)
