Gambling is still base on luck and nothing much can be said to dispute that. When you play a game, even when you know that the team is better than the other and they have the more tendency to win, don’t you see that the opposite happens sometimes. Someone will go and pick the mediocre team as the one to win even after fully knowing that they are not going to win. After playing the game, they’ll now be hoping the one they chose to win even when the odds are against them. So if they win those games, will you say they won based on luck or base on skills? Gambling is more explained as a luck base game rather than a skilled based game.
