Can you quit gambling if you make a life changing money and never go back to gambling?

I asked this because those who made some money through gambling near me always go back to gamble and they end up losing everything they once made through gambling.

Is it fine to say that people should not go back into gambling once they made high amount of money? Because the chance of losing that money again is very high, even if they don't use all the money to gamble at once, gambling can take it all back in time.

Have you ever won a high amount of money from gambling and managed to not lose them all back to gambling? And to date, you are still gambling?
