If a bet is "safe" then it's not really a bet but more of an investment.
Gambling is less about investment and more about randomness.
Well the bet which has the odd of 1.01 seems to be an easily predictable bet as the casino and bookmakers give this odd to the bet which has the highest probability of winning. The bookmakers know the team is strongest and 99% of the gamblers will bet on it, so they keep the odd to the lowest value.
However, in the match, nothing is certain and one in a thousand times the strongest contest (team can lose too and we call it an upset. If this happens, all 99% of the gamblers on bet with 1.01 lose their money. Also with low odds, gamblers are expected to bet with a larger amount of money as they know the loss probability is low.
maybe it's true what you say that the guy bet over $1 million seeing low odds 1.01 which looks like 99% win but in reality what he got was not 99% but 1% loss lost all his money. very sad.
this uncertainty at low odds teaches us to always not trust low odds but trust our own predictions more and of course keep using money we can afford to lose.
