All of the definitions had already been mentioned so it wont be that necessary to repeat on whats been said above.
When it comes to definition then it would really vary into each person because not all would really have that the same insight or views towards gambling.
Some would really just be for entertainment but majority would really stick out on money or profit making which is the real fact most of the time.
In the first place, gambling is for the sake of entertainment but due to other benefit or chances that it can give then people are
going in the other path.
