We're very good at women's rugby, and rowing. I'm not so sure about the sports you mentioned, like squash - but I think Georgecrabbe prob has it about right, in that some colleges are just more inclined towards sport, despite what their facilities are like.
If you've got any colleges in mind, check out their alternative prospectus', these might give you a good idea of how enthusiastic the students are, and whether their facilities are actually any good. If the college has one, you can usually find it by googling the college name + alternative prospectus.
