Gambler's conceit

Gambler's conceit is the fallacy described by behavioral economist David J. Ewing, where a gambler believes they will be able to stop a risky behavior while still engaging in it. This belief frequently operates during games of chance, such as casino games. The gambler believes they will be a net winner at the game, and thus able to avoid going broke by exerting the self-control necessary to stop playing while still ahead in winnings. This is often expressed as "I'll quit when I'm ahead."
