I don't really think you'll find a simple answer. But I would go with yes.
I have a good couple of hours on Chipmunks / Bulldogs / Viking Gliders but have not got a PPL yet for the simple reason that some/most schools prefer to start teaching from a blank sheet as opposed to correcting yor bad habits.
CTC will probably not take you on the cadets scheme is you already have a PPL but if you have a PPL/ATPL/CPL etc then you can join the other course they do
I'd say you experience in flying has shown that you have been interested in flying from a young age and can only be seen as a good thing
Good luck
