This rush is nearly equivalent to a 'gambler's rush'. Do you not think gambling is an addiction?
In what way are the rushes equivalent? In shoplifting, you're taking something you haven't paid for. The rush is the part where you're actually stealing and getting away with it. In gambling, you're not stealing anything. You're winning money, not stealing money. There may be a 'rush' while winning money, but it certainly won't be the same 'rush' as when stealing money.
Both feel good when winning money, perhaps that's not what makes them feel good.
Used to shoplift too much--until I got a job & turned 18, anyways. I consider it an addiction just like masturbation, video games, etc.
