At early age of mine as I could remember I was 10-11 years old I already knew how to play cards, but what the good thing was my mother didn't really encourage me to reall engaged myself in gambling.
That must be a good example of good parenting. When you are under age (hope in your country also 18 years is a legal age to gamble), that must be a wise decision not to allow you to get into gambling. Because, if you found good profits from gambling then you may plan to live your life out of gambling only but there cannot be any assurance your gambling will support you to live out of it. So prohibiting you when you were under age from gambling, must be a very good decision a parent could do IMO.
