Is going to a London Uni extremely important for good job prospects in finance?

Hi, I currently have 1 more option left on UCAS for uni choices. I'm applying for Accounting & Finance, and right now only one of my choices are in London. I've heard that connections are super important if I want a job in the finance sector and that the best chances of me doing that is to attend a uni in London. Is this true? If I were to apply to another London uni it would be either Queen Mary or City St George - if it were outside of London I would apply to Manchester.
They all have required grades AAA (I'm predicted A*AA) but Manchester's offer rate on UCAS says 22% compared to QMUL and City's 68%. I've already seen people get offers for my course at the London unis so would it be too late for me? as in if they've already offered all the places.
