In slot game, it's very possible to turn $0.2 to $10k which is really a massive jackpot but it very difficult to have such a win, only in rare occasions. What's easily achievable in slot gambling is turning $10k to $0.2, it's very very easy and not as rare as winning the $10k with such low amount. In sports betting, it's even very rare since there's no 1 game that can have 50k odd, except you are gradually betting on different game, accumulating and doubling the bet until you are able to reach such amount. It is still a very difficult task.
