I believe you heard the quote, which says "House always wins". This actually applies in the long run. You may get some profit in a single session, or let's say you have been winning for a week. But a single bad session is enough to bankrupt you if you do not play responsibly. It is important to do responsible gambling.

Yes, I have made profits a lot of times and I even managed to withdraw the funds. But we always end up losing our money in the long run if we continue to gamble for a long time. It depends on your luck.
