That's kinda my point though

in the 2015 finals we should've won in regulation but we actually got miraculously lucky (in the sense that it NEVER happens to us) when Higuain bottled an empty goal chance in literally the last play of the game.
In 2016 we probably would've lost if Rojo doesn't go full retard and gives the ref the perfect excuse for a red card that made the game 10 vs 10 and completely changed the dynamics of what was going on.
And yes, important games are usually separated by the finest margins, that's why I don't put that much stock on national teams not winning or not advancing further in a WC unless they got truly dominated and/or played like shyt the entire tourney.
