Special award in ISEF guarantees admission?

If an international girl won a special award in ISEF and has 2300+ SAT, could we say she is almost in Caltech?

Sorry for the format of the title. This is my first time to post…

No one can really predict admissions. People have mentioned that perfect scorers on the IMO get rejected from MIT. But she (you?) will probably have a pretty decent chance, at least more than the average international applicant, perhaps even more than the domestic applicant
