I hate it when people say "gl" anyway. They never mean it, it's just something they do to taunt you into believing that they use the chat at all. It's almost like a macro... start game, type "gl". End game, type "gg". Totally meaningless.
When you're playing a game based on luck, it might be "good sportsmanship" to wish everyone else "good luck", but (excepting Terminator games) only one person/team can be lucky. Wishing good luck on your opponent is wishing bad luck on yourself.
