Every gambler on a hot streak believes he can grow it into a fortune. He cannot. The table has to touch zero once, and a long red streak always finds it.
his name is Joe Blitzstein. Harvard statistics professor, and he put the whole thing on a blackboard in a free lecture.
your money is a dot walking between zero and the house. every bet nudges it one step. zero is a trap - land on it once and it is over. you do not get up with anything.
here is the part that stings. in a perfectly fair game, the bigger stack wins - not the better player. it is not luckier than you, just bigger. and bigger is enough.
he says your odds equal "what fraction of the wealth" you hold - nothing about skill. that is every account you blew up while you were right. the edge never paid, because the walk hit zero first.

the edge was never being right more often. it is surviving long enough for right to matter.
