Hello everyone!
I really appreciate everyone's suggestions and super helpful advice, it was so thrilling to me waking up and looking through all of your responses.
You are all so right, I should have applied to at least 2 prestigious unis, I went with 5 very safe choices and it was silly of me, I am a living example that no matter what grades you have you should try and apply to one/two place with higher requirement grades.
The reason I did not apply to a more prestigious uni is that I have a D in GSCE maths.
