In my opinion you don't need to forecast an outcome. You need to find an event that you can guess and allow to have a profit.
I would not care about forecasting and being able to guess some high odds. I prefer to win even small odds, even silly results is fine to me.
Its a suble and important difference because one thing is to guess who is the winner of the match, another thing is to guess a specific number of goals during a part of the match.
