how many things do I have to read

Well unfortunately, when using Arch, you will, at some point end up requiring to read a lot of something.

If that makes you hesitate, but you still feel like giving it a try, I'd say one good way is, install Arch using the Arch ISO method and go to https://wiki.archlinux.org/title/Installation_guide and read that once before and then, while installing.

• it is very well simplified (simplified by explanation, not by omission)
• it has handy links for terminology you will find in there, so you won't have to go around finding stuff all the time
• open the page on another device, that you like reading on
  • read it like you are trying to understand it and not like instructions
• while reading/installing it, if you realise you can't keep doing that, you have your answer
• if you managed to install it before getting frustrated at the Wiki, well, know that most Arch wiki pages you will look at, are as good or better than that and you can consider this as another distro you might use.
