Congratulations to Argentina, this team really deserves to be in the final despite the unfavorable issues following the chaos that occurred against the Netherlands. I saw Messi so happy even before the game was over, that was after Argentina led 3-0 over Croatia.
I don't think a 3-0 was all about getting lucky, they played their might to be on the Finals again but I hope they won't fall short this time just like in 2014. They might not be the favorite in this World Cup but they have the chance now and they're just waiting on who will won on another bracket. More chance to practice and to study opponents that they'll up against in the Finals.
I agree that Argentina's victory was not absolute luck. The players are fighting to play something good and score goals. Argentina proved really great, they managed to get their revenge when 2018 Croatia beat them by the same score.
