Absent a PPL, you probably have zero shot (at a Guard/Reserve squadron). With one, you have a shot, provided you rush the units, make best buds with the people there, and are just plain good. On the plus side, given your age, you have plenty of time to chase the dream of fighters and still have time to apply for transports and tankers when/if that fails. If you're on the hunt for fighter slots for a year, say, and you don't even get called for an interview, you know you probably aren't competitive and can shift your sights or refocus your future plans.
I'd say five letters of rec is too many, pick your best three.
