His blundering a piece is a direct consequence of his playing strength. A stronger opponent wouldn't blunder that piece, and thus would yield a better result against you on average at that particular moment in time against you with your current playing strength.
The only argument for "luck" in chess is the one ChrisV mentioned, that has to do with chess not being mathematically solved. It could happen that you make a move that even stockfish thinks is perfectly sound, but that turns out to be losing by force 35 moves down the line,
AND your opponent stumbling upon that very line. I'd say the chances of that happening are rather slim.
