Well I clicked on this thinking you were in your last year at uni, ready to tell you that absolutely there's still time, so I think you know my answer if you're in week one.
I met my best friends at uni in second term, one of them a week before the end of term and we messaged/video called loads over lockdown.
It's definitely never too late! Just put yourself out there, although I know it is tough at the moment with loads being online for freshers. Joining societies really helped me, I joined two of my favourite committees (in the February elections) and that really helped for meeting people and socialising.
