aspiring choices, KCL and UCL

Hi all!
Just wanted another opinion on my choices, for reference my predicted grades is an A* in maths and CS, an A in Economics and an B in Further maths (A*A*AB) and I achieved 9888877777 during my GCSES (9 in maths and 7s in English lit and lang)
I'm also eligible for a contextual offer due to my postcode and FSM.
I recently got a contextual offer for Bristol for Economics and data science - AAB, which was around what my current "safety" option was (Leicester ABB) and I'd choose Bristol over Manchester for this course (around AAA), which means that I want to replace them with more "risky choices".
I've already applied to Imperial EFDS (A*AA) and Warwick Social sciences and data science (ABB)
I'm thinking of applying to UCL statistics, economics and finance (A*AA) and KCL data analytics for finance and business (A*AA)
However, my personal statement is revolved around Economics and data science so I was wondering how much this would disadvantage my application.
Any advice would be appreciated thanks!!

When did you apply?

My application was sent on the 5th

If you're happy with your Bristol offer in the event of getting 4 other rejections then you have nothing to lose.

what's the process if I do get rejected from the other 4 universities? As though I do not mind going to Bristol, is the standard procedure not firming and insuring two different universities?

If you only have one offer you don't get an insurance.
