You have a hidden stat MMR - some number. There is an average or expected MMR value/number for the tier and division you are in, if your MMR is equal than that average/expected MMR you get a set amount of points for winning and losing; if it's higher you gain more than the set points when winning and lose less than the set points when losing; and if it's lower you get less than the set points on wins and lose more than the set points on lost games.

Example (these are NOT real numbers):

You are in division III of gold tier the expected MMR for that is  1900. The standard gain/loss for LP points is 15.

a) your MMR is 1900 = 1900 you get 15points for winning and lose 15 on lost game.

b) your MMR is 1800 < 1900 you get 10 points for winning and lose 20 on lost game.

c) your MMR is 2000 > 1900 you get 20 points for winning and lose 10 on lost game.
