The is the parental Gambling Influence
Gambling is a personal interest which meant for people who like to play or bet. Now if the Father was an addicted to gambling then the kids would follow up.
Not in all cases. Often times children who suffer trauma due to their father being addicted do their best to avoid gambling. But those that suffers nothing will more likely follow their fathers path.
What you do regularly and sometimes you even send your children to do it for you and all those processes they are learning from it.
True, but kids being exposed to gambling in early age with parents' guidance will make this kid develop a resistance to it. After all, it is about how the parents teach themselves about the matter of gambling. But in your given case, it is more likely that the kids will develop the same gambling habit as the father.
Then peer influence. Those children that are out of control from their house or family are influenced by their friends outside. That is why parents are advised to know their children friends.
Peers have the most influence on a person. Due to the sense of "to belong" a person even though not into gambling will try to engage in it just to make himself belong to the group.
Also social influence, the activities in the society also influenced children to deviate from the societal norms.
