Congratulations on all of your accomplishments in high school! You have a strong profile and will be competitive at nearly any school in the country. You definitely have a shot at Williams, but there are far more qualified candidates than there are spots, and thus there will be highly-qualified candidates without an offer of admission.
If you are deferred (or denied, though I’d have a really hard time picturing that) from Williams ED, make sure you have a safety that is affordable for your family, that you are extremely likely to be accepted to, and that you would be happy to attend.
Has your family run the Net Price Calculator at Williams? Is it affordable for your family? If not, do not ED there.
