No, a ppl counts for zilch.
They test your aptitude by teaching you to fly. You may be 'so good' during EFT that they re-stream you to WSO(N) or even Flt Ops.
If you are a natural, have loads of spare capacity, and able to assimlate training quickly you might go straight to Harrier or Typhoon. If your flying is methodical, uninspiring but safe then you may find yourself assigned to something more agricultural. I won't suggest what as it might offend.
However an Argosy was likened to a wheel barrow. Go figure.
