I think that's the worst thing any gambler can possibly do and most gamblers still do it no matter how hard they try to stop gambling when losing. If you intend to find closure by trying to gather your loses only God knows where thats gonna end you, you might end up losing your whole money so its better you just stop gamble when you are experiencing a losing spree because your emotions can also trigger you to loose more because at that moment you won't  be thinking straight so its better to close the gamble because chasing your loses can only result to one outcome which is more loses.
