Well it will onky be called job if you are work in a gambling site as a part of the team or you work for a real casino to play with the gamblers .but if you are only playing it is not a job its your choice ,Playing is not wrong
You have a good chance to make money if you are working in a casino because you are sure you will get paid since casino business is profitable. If that is your job you will always think that it is not a sin, instead you will defend it to anyone who would call it as a sin. That is your main source of income so it's just right to love your job and be proud of it.
