If I'm rich there's no need for me to gamble anymore I'd rather spend some of my money to satisfy my needs, it's a win win situation.
No, You need to be rich to be a gambler. How can you gamble if you have nothing to invest. however I decided to gamble for fun unexpectedly I won and I continue to gamble until I took the chance to take all my money to gamble and I lost because change purposes from for fun to profit!
But it is better to stay away from gambling if you already have the riches because it might burn all your riches once you are losing on way in
gambling. I have read and heard a lots of stories about rich gamblers that became bankrupt because of gambling.
