At one point in time, K/D actually had some relevancy or correlation to something. Nowadays it means absolutely nothing. I have seen players with K/D over 10 and are terrible. With vehicles and aircraft in play, there are a ton of players in double digits.
Take this player for example, K/D of 33.87 with 141,411 kills with the Nightbird. Most kills with a weapon, 1857 with M44. K/D is irrelevant.
