Why are some people so bad at this game?

This is not a rage thread about teammates or elo hell or anything, this is a legitimate question. Sometimes when I play some normals there's this one dude that makes me wonder: why do some people suck so much at this game? How can you have more than 100 losses than wins? How can you have 600 games played and still not know what a minimap is? Like, what goes on in the minds of people like this? Is it a legitimate mental handicap?
