Crap happens. I've had times where I was laying down fully automatic fire and people walked right through my line of fire and apparently juuuust right to walk through the gap between two bullets.
I've had times where I would shoot a Peacekeeper at someone's chest and the damage numbers told me I did 7 damage, which is a single pellet in the leg, which is rather improbable considering where I was aiming.
Other games got those kinds of "what you see isn't what the server sees" situations too. Like when you front flip into the ball in Rocket league and your butt just phases through the ball and everyone else just sees the ball wiggling a little bit and it keeps moving as if it didn't get touched because the server decided you didn't hit it after all.
