Can we really earn money from playing games?

I just wanted to know can we really earn money by playing games like rummy? One of my friend plays rummy and he has won cash many times but when I researched I got mixed reviews as per few of them online rummy websites are fraud.

And also there are some advertaisements to attract females to earn money in lakhs in a few days . These are all some tricks for imoral acts.

If you want to win you can go to TV reality shows and take part and win genuine cash prizes or attractive gifts like car tv  iphone  , refrigarators or world tour
