SEVP end date haven't changed

As of May 24, my employment end date on SEVP haven’t changed to Sep 30. Is it safe to say that I am not selected in the lottery? Would there still be any chances that I got selected but SEVP is not updated? Thank you!

That would depends on your OPT expiration date. if it is expired before Sep 30th, it may get changed to Sep 30th.
