I am not sure..
I also applied to the NSF GRFP and NIH F31 Diversity (longest and most excruciating application of all the fellowships). Hopefully I can get one of those and not worry about predoctoral fellowships for the rest of my graduate career.
On the results page, they said 70/2100 received the Ford, that's only 3.33% of applicants. Those are very low chances.
If I don't get anything this year, I will probably re-apply for the NIH F31 Diversity or AHA Predoctoral. Both of these have much higher success rates. The NIH depends on your field but its around 40% for me, while the AHA is 37%. Since it's a numbers game, I rather take my chances in those two.
