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!
meh, you don't need to be rich to gamble and if you become a gambler then you can no longer be rich. because being a gambler will lead to addiction to gambling and then losing all your money over to gambling and bad luck.
but you can always gamble for fun no matter how much money you have. you can make a bet with something like 10 bucks and have fun doing it.
