Yeah I'll bite.
It's pretty simple. Your application won't be processed until it has been completed and you have supplied all of the appropriate documentation required. In the three months it took you to send in your flying hours, all your application did was gather dust on someone's desk. Meanwhile, 150 odd good quality applicants pushed in front of you for consideration.
You're competing against high calibre people for a pretty small number of positions. Hundreds of people make it further in the application process every year. How do you stand out in a pile of 400 resumes? An OP1 gathers attention, not a 6. Distinctions at uni gather attention, not simply attending. Team sports, leadership positions within organisations, a significant interest in aviation. You have to tick every box mate. You don't have to be the best at everything, but you have to be pretty bloody good. You have to sell your potential, sell your ability to dig in and slog your guts out for a few years and never give in.
I'll tell you right now, your ethnicity has nothing to do with it.
Pick your grades up, work your way into management, volunteer when you can, play team sports, show more of an interest in aviation. Be ruthless in how much you want it. If it seems a bit hard, GA and the airlines are as equally brutal. The only thing is they won't tell you straight to your face.
