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'll answer this with a quote from James Russell Lowell: "Only dead people and fools never change their minds."
Stick to a series of numbers or a certain game for the rest of your life is boring. At that point, you play to win and you don't have fun. In the long run, you get bored or make dangerous bets, losing everything you have.
By varying your games and bets little and often, you create more opportunities to win and maybe find the one you enjoy the most.
But that's just my opinion.
