Understanding Poker Software

I need help understanding what it is I am looking at. Just a basic breakdown. If it is too much to reply back, then please send me a link. I see these used all the time in videos, but still don’t know what it is I am looking at. My short term goal is to improve my preflop action. One of my weaknesses is Ranges.
Why does this particular grouping of cards equal 19.9%?
How does this factor in to my preflop decision making?
I know that a person could make a career out of explaining poker software, so I am not looking for a deep breakdown. Just something to get me heading in the right direction.

    What you are looking at is a visualization of someone's range. If you are unfamiliar with what a range is, it's simply all the possible hands that someone can have at a particular point in the game. On the diagonal you can see all pocket pairs, above the diagonal the suited ones and below the diagonal the offsuit ones.

    It's 19.9%, because the hands that are highlighted make up 19.9% of all possible hands a player can have.

    This just tells you what someone's range could look like when they, for example, open 20% of the time preflop.

    Why does this particular grouping of cards equal 19.9%?

    There are 1,326 different hands you can be dealt in Holdem.

    Here are some of them: :AS::AD: , :AS::AC: , :AS::AH: , :AD::AC: , :AD::AH: , :AC::AH: . Those are all the AA hands, and that is 6 out of 1,326 hands or .45% of all hands. Do the same thing with KK for another .45%. Add the other pairs down to 55 and that adds up to 4.5%.

    Now repeat that process for the other hands highlighted in that table, and the percentage will add up to 19.9%.
