Of course we need luck to win but can we control our luck? If your answer is no, then's let's be realistic..
What we need is to learn the basics of gambling specially the risk associated in playing, by doing that you are already making an effort to know what you need to do to increase your skills. If you can continue to develop your method, you might have a chance to win in this game.
Just take notice that most gamblers loses because they do not have a long term plan, and we have to do what they do not do to have an opposite outcome which is winning.
