Hello, I’m only bronze but I’m loosing most of my duels because I can’t manage to do headshots… I’ve been training in the training field for a long time now but in it I can make headshots easily… What am I doing wrong? How can I make me do...

I am always queued with the best players that know what to do in any situation , will always know what position you take and will totally headshot you if one pixel of your hitbox shows up on their screen. Why??? Can somebody explain?
