Gambling is possible at certan NPCs. If you interact with the NPC, you will see a window with unidentified items. Only after spending some money on a specific item (by right-clicking on it) the item gets identified and you will know what its stats are. Many players regard this to be a waste of money due to the existence of "runs".
