I can't remember how much it was but that's not that much compared to those actually addicted gamblers that would be fine losing $1k in just a single spin or roll.
the researchers found that gamblers are satisfied with small wins and will tolerate small losses but when they hit the threshold of loss, they will not play anymore.
Both are true, we're happy with small wins and that makes us content and want to gamble again sometime. And when we lose, it's the temporary halt that we have to make but after moving on, we'll gamble again from that loss.
