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.
When it comes to gambling, whether or not the gambler carry out any form of research before placing the bets is not important and that is what makes the big difference if the gambler depends on just luck even though he has made a lot of game's analysis, this is why sometimes, analysis seems to be worthless and only luck can give the winning, this is very important because at some point we have all experience a similar loses even though we made a lot of analysis, their will fail at some point and when that happens, luck becomes the only considerable factor to determine who wins and who lose.
