What are my chances?

So basically I’m a university student who’s been applying for internships.

I’ve recently been given a referral from the CIO of the company, and he’s given a note as well to the hiring manager of that team. He gave me her LinkedIn and told me to message her and I did. She replied saying that’s she’s received my resume and the notes that’s he’s given and ultimately said she’s gonna review my resume and HR will decide if they move forward.

It’s been a week since that LinkedIn message and I don’t feel confident about getting it given all these positives. Realistically what are my chances?
