What Are the Chances of Winning One Thousand Dollars At a Casino Game of Craps and Why?

If a gambler bets one dollar at a time at a craps table, the odds of winning a thousand dollars before losing a thousand dollars are one in two trillion.

That’s a two with twelve zeros.

If everyone on Earth played this way, betting a dollar at a time until they won or lost one thousand dollars, and then did it over again three hundred times, only one person would ever win, and then only once in all three hundred times.
