Just got my first offer from Colorado State. Nice to have one under my belt and I don't have to worry so much about rejections elsewhere.
Looks like Uni of Washington has started sending out interview requests. Fingers crossed for everyone here.

Oh my girl, really be confident. It's about deadline and you should just go ahead with your PhD application without making big changes. Really forget about publications, how can undergraduates have top publications like Annals, JASA, etc. Look at
 for a detailed reference of publications. Build confidence by finding your advantages. I believe your cs background, research projects (shown in RLs), passion for research (show it in your PS!) and gender are sure to make you stand out from PhD applicants!

@Dandelion_97 Very few PhD applicants in statistics have any publications. It’s difficult to get involved in statistics research without a graduate degree in statistics.
You have a very solid profile and you should be able to get into some great PhD programs. Since you’re an international student and didn’t go to a super famous university, I think you’ll have a tough time getting into CMU. But you should have a good shot  at TAMU, Penn State, NC State, Ohio State, etc.

As mentioned above, I would not worry about publications. Very few applicants have them. It certainly helped me to have a submission under review at a journal as it reaffirmed my research ability. However, I needed that to make up for poor academic performance one semester. I would not worry about this whatsoever.
My previous recommendations and comments still stand. I'm excited to see where you end up. 
Best of luck!

If your school isn't #1, I think you'll be okay if the name carries weight, in my opinion. 
As for your list, I think you may be underselling yourself a little bit. I would look at adding a few more mid - top tier schools. Schools like Michigan, Penn State and Minnesota may not be bad to add.
Personally, I can speak a lot to South Carolina. I think it is probably a safe bet given your profile. 
Currently, my brain is split between a proof I was working on yesterday and writing this (damn your Dirichlet distribution!) so I'm sure I'll write a follow up later with more schools. Hope this helped a little.
