Someone explain this to me

I had an Ezreal who was 19/3 30 minutes in the game. They have a Leblanc 17/6 30 Minutes in the game.

Ezreal asks how comes we fed Leblanc.........Instead of asking how comes he has 19 kills =.=

If the enemy can feed you then you have to expect that your team might feed as well. It's just a way of life.
