I'm certain CC (or Cee Cee as I've seen listed somewhere else) has had a similar talk with another hooker or two before. Each time it probably happened towards the beginning of the "relationship", when things were still fresh and there was little history of discord between them. As for whether he actually believes this or was lying I think the answer to that is a little more complicated. I don't see him ever going to Paris but I think he himself believes this is possible even if he knows deep down it is not going to happen. This is CC letting his guard down somewhat and revealing his idealized version of what he could be. This is his moment of indulging in all of his big talk of these major dreams he has. Most of us have been there, talking about all the things we are GOING to do. Often that talk involves the promise of finally leaving that dead-end job and doing something that we always wanted to do instead. But rarely do we do this and CC is no different. Granted he realizes he can't be pimping forever and he probably doesn't like the lifestyle anyway (nothing glamorous about being a pimp), however it is doubtful he has the will power or character to pull himself away, not unless something forces his hand. Thus the talk he gives Lori is not just something he thinks she needs to hear, but more importantly something he needs to hear most of all. It is a way of convincing himself that he is more than just a pimp, that he has a greater destiny ahead of him, that something better is waiting for him. The hard truth for CC is that the only thing waiting him is jail, a terrible death or at best, if he goes clean, an average 9 to 5 job.
Gary Carr is knocking it out of the park, delivering the best performance on the show. His character is full of contradictions, insecurities, and street swag. Despite how terrible he can be he is a magnetic force that you can't look away from.
