Let's say when gambling, you follow a specific pattern. Let us use lottery for example. You bet on the same specific set of numbers. What would be more regrettable? Betting on the same set of numbers for the rest of your life and not winning or... changing up the set you bet on only for your old set to win?
Basically, would you rather bet on the same thing again and again then regret not exploring more or explore different kinds of bets then miss out on a win?
I won't regret whether I choose to bet the same set of numbers or keep changing the set because it doesn't really contribute much in the probability of winning the lottery so it all comes down to the luck part which we can't influence at all. So just bet as you wish irrespective of what others do and who knows you might get lucky some day. If you didn't win at all then no worries there's millions of people out there who didn't win.
Now let's use dice for example for even better understanding, you choose number one and decided to stick with it for all your bets then you can't be sure that there will be 1 win our 6 rolls because each previous roll is irrelevant to current one and every bet has the probability of 1/6, and the same goes to if you change any number you want at any time, there will be no pattern it all just random events.
