I play blackjack as a hobby. Blackjack is somewhat unique among casino games in that your skill can have a dramatic impact on your results. What you call luck, professional gamblers call variance. Things can go extremely well or very poorly in the short term regardless of skill, but over the long term, variance ("luck") becomes meaningless and skill becomes the determining factor in the player's results. This applies to any game where skill can affect the outcome even slightly, and certainly includes the startup game.
