There's a saying in the casino world which goes 'the house always wins,' which implies that no matter if individual gamblers within the casino take home more money than they came in with, it's the casino which is the ultimate winner overall. The ultimate confirmation of that fact is that the people who own large casinos tend to be very rich, like Stanley Ho, who operates on the gambling paradise island of Macau. He has so much money that handing $7bn to his daughter Josie was no hardship for him at all.
Ho used the money to get singing and acting lessons, much to her father's disapproval. He hoped that she'd follow him into business, but she dreamed of being a singer or an actress. In the end, she's achieved both, having released records in her native Hong Kong and appeared in a number of Chinese-language movies. She has occasionally made it into Western cinema too, such as 2011's 'Contagion.'
