From my experience the first time pass rate and average pass mark are only important if there is a possiblility of being recommended to an airline by the FTO where you took the exams. For example, OATS, Cabair (that I know of!) Outside of this other avenues of employment tend to look at more than this. Mainly flight hours, but also personality and flying ability through psychometric testing and sim checks.
But dont think the world has ended because you had to re-take a few of the exams. There have been plenty of post from those with jobs who failed exams, IR's, etc. and still made it
