pretty much every game since Half-Life's patch in 2000 uses client side hit detection for hitscan weapons
a few do client side prediction for projectiles too (Overwatch notably)
IMO, This is clear-cut evidence that PUBG uses (or perhaps, in the past used) client-side hit checks. Notice there's not even bullet travel time. Just "pop pop" and a target that isn't in sight and never was inside instantly dies.
