In an honest sense everything in life is a gamble. Just the risk is different. We are playing with chance in every aspect of life, just from the moment of being born from the womb to the tomb. Still we develop skills and try to game the system to our advantage.

The attitude to gamble comes from willingness to take the risk. This is something that anyone likes to do and thus gambling is an inherent nature of humans.

Whenever there is something at stake, and it is always there, it is a gamble. Now a sports game may have odds in favor of those who know the game and their expertise and not completely luck based.
