From the data point of view, the probability of winning or losing is the same, and winning or losing is between four people. But now the society is a paid service, and one of the service fees (Taiwan fee) may be ignored. The probability that he will win is 100%. It seems that he doesn't smoke a lot, but the number of tables in a restaurant ranges from a few to dozens. How many cigarettes does he smoke at the end of the day? Even if a few friends go to get a room, the cost is included in this fixed consumption. Coupled with hidden consumption, the consumption is even greater. If you don't play cards, you may only smoke half a pack of cigarettes for half a day. Playing cards for half a day may not be enough. You don't play cards or pay attention to drinking tea and eating at home. I know that it is normal for some bosses who open the door to spend hundreds of thousands a year. A mahjong room is usually played by neighbors. If there are fixed 10 players playing cards alternately, and a platform fee is 10000 yuan, then your 1000 people will be 1000 yuan on average. Judging from the accidental law of mahjong, it is normal that 20% people win, and 80% people lose more (plus the current professional players, you will find it in almost every restaurant). .......

To sum up: quit gambling! Is the best policy!
