The danger in giving stats is that people either think the odds are against them or in their favour, when in reality it depends on a lot more than luck.
In my AFCO fewer than 50% of applicants score high enough for NA(ACMN) in the recruit test, not that they are all applying to join as ACMN. About 90% pass the interview, and about 80% pass the AFCO medical. Around 95% pass the PJFT. Nationally only around 10% pass FATs and around 50% of those passing FATs actually pass the Inititial Aircrew Medical Examination IAME).
Since direct entry aircrew was introduced, the only applicant to get as far as passing IAME had to withdraw their application due to injury, prior to entry in my AFCO. My AFCO is one of the busiest in UK.
Hopefully that's boosted your confidence no end.
