If you are going to work on bikes, you will need to learn some of the jargon like we all do. I use the Park book so I can have it right there where the bike is and look and read and look. Look to see if your high/low screws are actually touching anything. If they are, adjusting them will make a difference. The first time can be confusing but each time gets easier, though I still use the book to get the order of adjustments correct. Keep at it, you'll get it.
