Is it possible for HR to reconsider a rejection, even with a referral?

I recently applied for a data analytics role at a company where I have 2.5 years of experience and received a referral from one of their employees. However, I received a rejection letter yesterday. The employee who referred me mentioned she would forward my resume to HR again. Realistically, what are my chances of getting a call? I noticed that the position has been removed from the company’s job listings.
