I dunno about that particular project, but it's a common thought process that some people can be shown something better, given the opportunity to achieve something by honesty and hard work and thereby leave their old criminal pasts behind them. Does it work? Yes and no. No for the majority it doesn't ( completely anyway) not because the idea itself is not a good one, but because the people concerned cannot or will not take it far enough in their personal social lives for it to make a difference. When it works it usually works because the young person concerned removes themselves totally from their previous social group, thereby giving themselves space to really focus on their future without third party interference or judegments by friends or family. It's like being a drug addict, you'll always be one however hard you try until you divorce yourself from other users. Criminality is no different.
