Sub 1k yeah I could see the gamble paying off, but beyond that? The moves at the bottom of the pic tell the tale- Bishop to c5 takes knight, pawn to d4 blocks a check, likely bishop to d4 confirms the mate. Even aside from that, its something like a 13 point material advantage, along with white having a locked up rook. Even without the blunder that's a rough situation.
