No UK University will look at 'just grades or scores' for Medicine.
Admissions to UK Medical Schools is regulated by the General Medical Council which lays down specific criteria ('professional behaviours') that the Universities must look for in recruits. Therefore, your Personal Statement is a crucial part of your application and this will decide if you get an interview or not.
Academic ability is not enough - you must show why you want a career in Medicine, and not just because you 'like science', and give examples from extensive work experience in clinical settings, and volunteer experience in care environments, that show your altruism, communication skills, ability and perseverance under pressure, and your experience in dealing with a wide variety of people, etc.
In my experience, many European applicants write very 'lightweight' statements that describe their school work and hobbies, but don't go into any detail about their relevant experience or their motivation to enter a caring profession.
Ask the Uni for feedback - they won't be able to do this until May, but it will give you pointers for how to improve your application for next year.
