Congratulations to you, you surely got lucky on that one, and this is an example that shows that gambling is nothing more than a game of luck where only those who get lucky can win some money and manage to withdraw and use that money for anything they want, but most people still don't understand this and they strive to win by using large amounts of money without realizing that more money doesn't guarantee any wins.
Some people believe that you can be successful in gambling if you have a lot of money because you can easily recover your losses when you have a back up, but that isn't true because I have seen people losing millions of dollars in gambling without winning anything only because they tried to chase their losses and gain success in gambling.
Yes, that's what the OP did, he played to get his money out of the free bets so he didn't care if he lost and lost, that's precisely his mindset, not for winning, so he played carefully because he wanted to withdraw his money and win enough money to be able to withdraw it. In fact, if all gamblers had a mindset like that, they would definitely play very carefully and not go beyond the limits in proper control, knowing which ones to play, not only luck but their self-control is quite good, apart from that OP also wanted to withdraw his money so he managed to withdraw it and was quite money for that. but it's true that it all comes back to luck.
