What can u say about people depend their fate in gameshow?

I think many people are playing fate when they go into these gameshows. One most perfect example of a gameshow I can think of is "Deal or No Deal". I feel on this gameshow people are taking a lot of unnecessary risks just because they can, and most of them end up getting less than what they bargained for. A lot of them say "Oh, it's alright...I started this game with nothing in hand" or "I'm just here to have fun" which is justified, but I mean if you could have won a bigger amount why take the risk? I think people are just greedy in nature and if there's a larger "fish" at stake they are willing to give their all for it. Your advice is good too, we shouldn't depend on these game shows too much, but it will certainly be a good experience if we can have the chance to enter one.....
