This is true, and it can be helpful if someone understands that in gambling, there is randomness and no pattern because if there were patterns, the world would find them out and then everyone could win their bets based on the patterns they have learned.

We often see people being delusional when playing a certain gambling game. They think that they have found some pattern that can make them win, this is specifically for games such as roulette, high-lo games where cards are involved, and some others. They look at past results and think they can guess the next outcome, and if they lucky guess a few right, they start thinking they have found the pattern that they can use to win now. However, they lose everything eventually because their pattern doesn't work.
