Don't get too hung up with the stats. Oxford get u a licence, you get the job. The Oxford ticket carries a lot of weight and gives u the best chance of getting a job but its u that has to have the right qualities to be employed by an airline. If you do well at Oxford and pass most things 1st time, get a good grade average, become a good pilot AND you'll fit into an airline environment then you should get a job.
Think whether u have the qualities, drive, and determination to succeed at a demanding course and in a competitive market.
