I'm afraid I could defeat my parents.
We know some of our parents aren't in gambling before or maybe hated gambling, so if we know already how they treated any gambling activities, it is good to be not with them when we gamble. This is the reason why I never play with them, better preferred to play against my friends or office mates.
It also depends with other parenting styles, not all parents hated gambling because there's another type that they treated gambling as family bonding. One example to that is the card games, which they only used small amount of money used to bet. Nothing serious that matters, but only for fun games with small money involved. Sometimes it became that hated with other parents when their son or daughter became addicted to money betting which could demand money from them to maximum need.
