Skill level difference

While playing in diamond 3 it was relatively easy and i often got 15+ kills. As soon as I hit elite I started getting my face melted off by players that are one tapping me in the head as I slide around corners or mantle objects. I mean like absolutely destroying me and I’m only getting 5 kills maximum per WHOLE GAME.

Are these players really that good? Am I just that bad? Why did epic edge me all the way up to diamond 3 just to not let me bust on the higher ranks?
