Source & more detail information: https://en.wikipedia.org/wiki/Gambling_age#cite_note-27The legal age for gambling should be the age when the person becomes adult, as they are more mature and wise enough to take their own decisions. Children don't know what's good or bad for him and gambling can make any person addict very easily whether it's a child or an adult. So according to me the age of 5 is a bit out of ordinary for me but thanks for informing us about this.
