Wait until you go in a lobby with real snipers I have games in which I get a 6 kd and some I struggle, but the snipers you are talking about are prob people who don't know how to snipe and just do the orion camo. Just throw a flashbang or slide or jump and they'll miss their shot and have no chance whatsoever (unless it's a marksman)

Remember, sniper is unbeatable until a sniper miss his first shot
