If i will bet $1.000.000 even with such odds, i will analyze everything i can, even if someone ate an ice-cream a day before. For someone it can be just a standard bet, someone can make 10-20 such bets per day. Without additional information we can`t count the result.
There is no way for us to know if this gambler has done his own research before placing that bet but what's for sure is that the odds can't be lower than 1.01.
Also, we should not forget that the odds providers do their own research too and they are definitely more resourceful than any regular gambler. So, it's unlikely that he will find an information that the odds provider doesn't already know about.
I agree with you with the main part. But have to mark that there are situation when the casino mistaken. It is true mostly for low leagues with bet limits and casino mostly make a return of the bet, but i`ve got tasty odds and win on such events.
Here i don`t think that there is a chance of a mistake, but i meant that i will try my best to be sure that it is impossible to lose such money.
Yes we can assume that it's a mistake or even intentionally made by the casino itself to make bettors confident in the possibility of winning, but basically we don't know how to verify that about the casino with its research, the lower leagues are more difficult to predict in my opinion, unless you really understand the team that is competing compared to the betting provider itself, maybe you will be more able to take advantage of the opportunity.
$1 million is a lot of money, it might even take us a long time to collect it, I also can't lose that much money in betting, but it's subjective about the risk each bettor takes.
