I still believe that there is still luck, even if the game is base on the number on a card that will be given to you, I know that even if a game still needs a strategy you must still need luck for you to win and for you to make it easy. There are times that even if how good you are already in gambling, there are still times that you will go home nothing.
I am not saying luck is not there. It is there in every aspect of life but the EV+ games can be relied on skills but luck obviously plays a factor. Again in card games there are counting skills and ways to bluff the opponents so its not completely luck based unlike an EV- game like dice and slots where the casino will win in the long run.
Going home with nothing should not be thought as a defeat. It is a part of gambling and one does not lose completely or win completely. That win or loss only temporary until their next visit. That is of course false for those who would never gambler again - which is rare.
