Those groups of people who claim to know the future are charlatans which equals to plain words, fraud. They should be identified and called out.
But here who are defrauding? Yourself if you think you know what the game's outcome is going to be. Intuition is useful in things that are not based on luck like skills based work and detective work. But when it comes to gambling everything has a luck factor in it and your background homework means nothing to the game.
For the gambling industry to thrive making such habits run is good for them, the more you try your "intuition" - you are essentially running with what you like, making the result same as someone without intuition.
Intuition can be combined with analysis, let's say you analyze an event and find a good bet, but at the same time you have some internal doubt, this may be intuition and it is better to listen to it and not make this bet.
Or if with the choice of the bet intuition tells you that this bet will definitely play, then it means you can play, only in this case you should definitely not give in to euphoria and bet more than you have determined for yourself for the bet, in gambling unexpected results very often happen, even if intuition tells you that everything will be fine.
