You've been winning a lot of from poker and casinos because you are good it at and you have develop a skill on your own
Are you willing to teach your children your secret and skill if you are good at it? so if they gamble they will also come out a winner like you?
I will not ever try to teach my future children on how to gamble because I know the consequences of it, if someone was drown in gambling it is very hard to comeback again and I don't want to see my future children drowning on this so what called gambling though I know the feeling of it.
It doesn't matter if you are good on some field, the thing is if that field will be able to help your children to grow better.
Yes we should teach our children only those thing about what we are sure that they gonna make bright future with. So if you are talking about being good gambler so just learn about the game you want to gamble and be ready for the rise and fall or I should say lose and win. Children should focus on study only and if they are in trusted in gambling so firstly they should learn gambling.
