It is not wrong to take a temporary break from gambling, it is up to you to decide what you want to do, you can even request self-exclusion if that is what you want, though that route is mostly for people with addiction issue or people who feel they are spending too much money gambling.

If you win some money, you can withdraw some of it and leave some of it to continue gambling, taking a percent of your winnings gives you a good feeling and you can try again with the funds still left in your account.
