Means that you came to this gambling industry a bit too late. I say like this because casinos used to give new players something called by "No Deposit Bonus", where players were given an amount of their account balance and they can use it to play the balance without making any deposit. The balance is locked of course until a specific wagering requirement is met. Once balance is unlocked, players are able to use it as they wish, whether to continue playing or withdraw it. However, this type of bonus is no longer being used by most casinos because there were too many abuses by greedy people who tried to make money for free from this type of bonus.
