Gambling can change the course of your life at any moment. It is the shortest path to success in life. However, the amount of success and failure is equal. No one can say you will succeed or fail.
Do not be tempted to see someone can be successful or can achieve a win with a huge amount that will change his life because it is very possible that he has been through it long enough to be able to achieve that and also the money he uses is also big, no one knows only he knows.
I think he mean those user that manage to win a big time jackpot by using small amount of money on game with huge win multiplier such as lottery, slots, sports betting parlay and etc which can change the fortune of the player if he manage to hit a max win or jackpot using a 1$ or 5$. We know many stories that a normal guy turns to millionaire by hitting a jackpot using small amount of cash.
