Interviewer for internship hasn't got back to me, but has to other candidates

I had a second round interview for a internship on tuesday as a junior software developer. The first interview was the technical interview, this interview wasn't really a interview, more of a chat. The interviewer spent 45 minutes showing me their main product, giving me information on the company and asking me questions such as "What do I expect from this" How much do i expect to be paid" to which my answer was, I'm here to learn, so the money aspect doesn't bother me. The interview lasted for a bit over an hour. I was told they are taking on a few of us.

My concern is that I haven't heard back, while 2 other class mates have secured the job. She said I will be contacted in the next day or two, and I haven't been contacted and I' anxiously waiting for my phone to ring, or emails to come in. I'm going mad be anxiety.

Do youse think I haven't secured this internship, or there might be a chance
