1X2 is the classic match result market: Home win, Draw, Away win.
1 = Home win. X = Draw. 2 = Away win.
Football draws are common, and markets price them carefully. Seeing all three probabilities helps avoid distorted thinking — for example, the assumption that "one side has to win." When you see all three outcomes as probabilities rather than a binary choice, you get a more accurate picture of what the match looks like.
