That's not true at all.
In all of these sports, the team that scores more points wins the game. So does that mean that we credit the amazing defense of every team that wins, because they held the opponent to fewer points than they scored? Of course not. There are teams that win because of strong defensive play, and other teams that win with OK defense and strong offense.
The goaltending isn't the only factor of defense so I still stand by my point. You are the one who tried saying the better goaltending almost always wins.
