How likey am I to get an unconditional offer from University of Edinburgh?

Hi everyone,
I am a Scottish student currently taking a gap year, I want to apply for MA Finance and Business at Edinburgh. I will list my achieved Scottish qualification grades below:
Advanced Highers (All A's)
-Maths
-Physics
-Mathematics of Mechanics
-Chemistry
Highers (All A's)
-Maths
-Physics
-English
-Engineering Science
-Chemistry
National 5 (9 A's)
I am wondering how likely I am to get an unconditional offer from Edinburgh for Finance and Business course since all my subjects are STEM related. And also do does edi look at grades more or personal statement?

How much do you exceed the standard entry requirements by? Are there any required subjects at Higher or Advanced Higher level that you don't have?

Standard entry requirements are 5 A's at Higher with no required subjects
