Why can gamblers never quit gambling?

In the early morning, I took Didi with two female passengers—she was just heading home after staying up all night gambling. One woman said that last night she lost six or seven thousand.
She said that at first she only bet a hundred or two hundred, but she kept losing. Then she started betting three or five hundred, and she was still losing. So she began betting a thousand at a time—she ended up losing six or seven thousand in a single night. After thinking it over, she said that it’s because you bet too little that you lose; if you bet big enough, you can win back a little in one win.
She also said she came specifically by taxi from the neighboring town to gamble. In 2024, she had already lost 10w. Then she talked at length about mahjong. I watched her look at gambling, and I guess she won’t be long before she goes into worse things.
Betting too little is why she loses; as long as you bet big enough, you can win back a little in one win. There’s already no saving her.
