What if he was holding cards while discussing with his friends because I saw someone's feet in front of him.

We also don't know if the photo shows him playing gambling with his friends and making bets as reported or if it is an old photo. The photo doesn't show any money and it doesn't look like there is a table to put the cards on either. And while that's true, I think he's out of his mind because gambling doesn't give you fast money.
