As a newbie its easy to play on casino games than to bet on sports since sports requires a analysis to understand the odds and of course you should be more familiar about the sports you are betting with. Both are still gambling, so technically making money is not guaranteed at all. To play on casinos you just need to read the instructions every game, have fun and make some money out of it. You just need to understand that you should only gamble free money and don’t be greedy.
