Is it adopted from a Korean TV drama?

There was a Korean TV drama called "All in", and it was a hugh hit in Korea and Asia a few years ago. This TV drama was filmed in Korea and Las Vegas, cuz the story was about a famous Korean gambler. Reading the casting, most characters in this movie are poker players and casino staffs, so I think it may be the adaptation of this Korean TV drama.

The synopsis of drama 'All-in' is as follows: Kim Chi-soo is a professional gambler a.k.a. hustler. He travels around cheap gambling dens with his young nephew Kim In-ha, gambling and hustling to make a living. In-ha grows up under such circumstances, and eventually ends up as a "partner-in-crime" with his uncle.



In-ha also picked up the skill of gambling, and as a young teenager, his hands became quicker than the eye. He has a bunch of friends and they are street kids who hang out in the poor area of Yong-doo Pu, committing petty crimes and getting into fights.



During one of Chi-soo and In-ha's narrow escapes from their usual gambling escapades, in the train on the way home, In-ha meets a girl named Su-yon. In-ha steals from the food cart, and is questioned by Su-yon for stealing. When they get off the train, Su-yon is robbed and loses her precious music box left behind by her dead mother.



Su-yon is travelling to the city to look for her father who works in a cinema screening movies. But she meets him just in time to see him get beaten up by gangsters over an unpaid loan. She moves in with her father in the cinema....
