As for 50/50 what i was trying to get across to you is that you will always have a 50% chance of winning, As for skill i meant that there is a element of skill required in the game such as denomination 
This line is nonsense. If Player A has a 50% chance of winning and Player B has a 50% chance of winning, then there is 0% left for skill. Either each player has a 50% chance of winning OR there is skill involved...there can't be both unless both players happen to have identical skill.
