This is rubbish, you need to go to a 'good' uni, sure, but this doesn't necessarily mean a Russel Group uni - go to one that is considered to be good in your subject area.
Work experience, a decent 2.1 or above, extra curricular involvement (positions of responsibility, team working, etc.), a pro-active approach to improving your employability etc. will count for a lot more when it comes to job hunting.
