Gambling will be his first mistress, the most important thing in his life. Like an alcoholic who will do anything for a drink, he will do anything to shoot dice, play cards, or bet on horses.

Gamblers are usually very secretive.
And they can be mean when they are losing. Remember, there is a nasty characteristic called greed behind gambling - wanting something for nothing. It will end in heartache.
