Offer grades higher than predicted

Hi I’ve received an AAB offer and am a little disappointed as I hoped to be given some leeway for sport performance. I’m also concerned/confused as I am predicted ABC so am wondering what happens if I don’t get the extra grades, is there a chance of still being accepted? I did the AASE course which is supposed to be equivalent to a B but offer says GCE grades AAB so am I right assuming the AASE points won’t count?

I am only applying to Loughborough.

I am trying to figure out why I’d be given an offer above my predicted grades
