Worrying about Employability [Bsc Economics and Politics]

Hi everyone, I've applied to multiple unis and received offers (yay) for Econ and Politics, both fields I'm really interested in. I was initially happy with my choice, but have been essentially told by everyone that I should have just gone for a pure Economics degree and that I wouldn't be able to get a job in the Econ/Finance sectors [If I decide that's for me] since I would be outcompeted by people with pure Economics or Finance degrees. Is this true?
