Will I get rescinded if I don't get the IB Diploma?

SO I got admitted to Berkeley but they want me to submit ALL of my IB scores. Idk if I’m gonna get the diploma though since I feel like I did horribly on my Extended Essay and I might not do so good on some of my IB exams. I also failed one of my IB exams last year but I didn’t report it since the UC Portal said I didn’t have to. The big problem is that I put on the UC application that the diploma that I will receive is the IB diploma. Also wanted to note that I am not an International student and that I will still receive my American high school diploma.

The conditions of admission for Berkeley states that IB scores are only used for IB credit but I don’t know what they do if I don’t get the diploma.

I’ve been searching online and I can’t find any answers to this since everyone is having conflicting answers to this problem.

I’m panicking right now and idk what to do.
