Your post reminded me a 2008 Bollywood movie "Jannat" in which the main character is very ambitious and wants to be a rich and powerful person. He is extremely talented in betting in cricket matches. He also manages to fix cricket matches. Ultimately, he is killed in a police encounter. The lesson of that movie was not to take unscrupulous means to get success.
Life is also something like gambling. One can never be sure what his/her action would bring for him/her. We play and sometime we lose and sometime we win but when we put everything in a bet, it becomes the most important moment of our life.
