I've gotten stats like that but definitely not for being AFK - but because if the match is one-sided and it's gonna be a loss for sure, someone will depart and bungie will always, and i mean ALWAYS load me into that match at the end, five second before the other team defeats their primeval so i can take the loss. Started happening when I reached legend on my 3rd reset attempt. So at the endscreen like the one you posted I show up with zeros across the board and i'm sure there's "teammates" thinking i was there the whole time being AFK costing them the match when that was definitely not the case. From their point of view, gambit/gambit prime is so hectic it's hard to remember all your teammates names and who was there from the beginning. They should maybe add a stat showing how long you were actually in the match so you don't get mistaken for an AFKer.
