Well, at least you tried out of thousands or millions who participate in the game it is still worth to try though. Don't just think if you've got a chance but at least you tried your best to win even though it is more based on pure luck. Even if your chance would be 50/50 like in the dice game you wouldn't still gonna win to that. The more odds you want the fewer the prizes that you gonna win.
I agree with you, it's not bad to try something new but only in amount you afford to lose. You can try site that even offer you to be a President if you are lucky enough. There is always a chance of winning and you don't know if you are extremely lucky. But I'm going to suggest everyone not to fall on such a sweetest dream, stay your mind awake so that you won't be on a dreamy things forever.
