One of the first lessons to learn is how to ask questions.
The doggedness on tripling down on “I want to know everything” is remarkable but it is not going to get you a result.
Your best starting point until you are able to articulate a more focussed question is the Arch wiki as already suggested.
Do a bare bones arch install on a PC you don’t care about breaking (a very old one with limited hardware perhaps) while following the arch install instructions on the wiki.
If you’re a noob then you’ll constantly run into terms you don’t understand look them up as you go.
