Way back in like 2006 when I was in middle school, a friend of mine pulled me aside to tell me there's more than just Windows and Mac. His parents worked IT and they showed him a lot of stuff and he showed it to me. I installed Slackware on a laptop with him. I basically just did as he said.
In high school, I looked more into it and tried installing some other distros but landed on DSL as the laptop my parents got me was a piece of shit and it worked good enough. I moved onto Ubuntu later because DSL can only do so much and really struggled with it lol.
And then as the years went by and Ubuntu started to suck I moved onto a variety of other distros like Arch(which took me 2 days to install and I fucked it up), Void(which also took me 2 days to install), Mint, and when it finally came out I tried things like SteamOS, Bazzite, and Nobara.
This all as I was dualbooting with Windows. I never took any classes, I never read any books on it, I just figured it out by doing it, breaking my OS a bunch of times, chatting with friends and randos on forums and Reddit, and the man command, thank GOD for that. All that and I just come back to Mint which I adore for its ease of use.
So all my knowledge is muscle memory. What the actual fuck does a package manager do? Like I know generally, but there's more to them than just downloading shit? What is the difference between Systemd and OpenRC? WHAT THE FUCK IS HYPRLAND OR WAYLAND!? I DON'T UNDERSTAND! 20 YEARS AND I LEARNED FUCKING NOTHING!

I recently had to restore a backup after a btrfs partition failed and became permanently read-only, and just for fun I tried to restore the backup of the broken partition to working order and read through tons of forums and spoke on the #btrfs libera chat with the experts and at the end of it this is my advice:
Do not use btrfs, use ext4 instead. btrfs failures are unrecoverable and they don't care.
I ran a software RAID5 via LVM2 and when a failure occurs it becomes some voodoo magic that not even the maintainers understand.
Lost 6TB of archives.
Guess you learned, but the rules of backup are 3-2-1 with at least one offline (I count offline HDD as a different media type for 2, tape one day, maybe, seems painful), it's not a real backup until you've restored from it and, RAID is not a backup.
It was just my media rips. So to say it was "lost" is a bit dramatic I suppose. I just had to spend another two weeks re-ripping my DVD and Blu-ray collection to restore the lost archives. (Without the RAID this time lol)
Sounds like bs, maybe your specific problem was unrecoverable, in general they are.
