Good!!!!
This is actually how some bettors are making money... identifying in smaller leagues or less popular sports when the odds are "out of line" with the real probability of the final outcome.
But many newbies see this same opportunity and end up making two big mistakes...
The first is believing that every value bet is a winning bet... sometimes you will find a odds of 3.0 when it should be 2.5. Its an opportunity but it still has a 60% chance of going wrong. So the profit is always in the long run, with repeated good decisions... that is where the edge will appear.
And the other mistake is believing its easy... that you just open the website and find a "strange odds" and bet on it... it isnt quite like that... you need to research, follow the statistics, injuries, etc. to see if there really is a real advantage there... its not easy, often it is not obvious just by looking at it at first.
Value bets are perceived as mistakes made by bookmakers, so it is seen as a cheap means of beating the house. Newbies might see it as a life-changing opportunity which might make them bet with an amount they cannot able to afford. A few years ago, a gambler had to borrow a huge amount to place a bet because he assumed that the value bet would make him rich. But it turned out the favourites lost the game and he became highly indebted. It is important to still gamble within your means even if you think you have found a value bet.
