Would AI become a huge threat for casino operators?

Two news items about card games caught my attention recently. One is about a Chinese woman who took away about HK$160 million in winnings from baccarat tables in several casinos in Macau. The other one is about an artificial intelligence (AI) called Libratus, which managed to beat four of the world's top Texas poker players and won chips worth US$1.7 million in a 20-day marathon tournament. With regard to the mystery gambler, casino operators were dumbfounded. "She kept winning over HK$10 million every day, it's so unusual," the head of the Macau Frontline Workers Association was quoted as saying.
