How likely am I to get into a good uni for Economics?

I'm Currently year 12 and looking to pursue economics at uni (preferrably one of the lower ranked russel group unis) I take maths business and finance at a level and I was wondering if my low gcse results will enable me to go to a russel group or a good uni. As a note my work experience predicted grades and supercurriculars are extremely strong. (For context I have 9 gcses or equivalent with 5 6s 1 5 3 4s with 4s in english and history and a 6 in maths)

AAA post academic comeback however i could probably get an A* in finance if i lock in
