Interestingly, I don’t see a “calendar” on their website which shows a date of release. So it’s possible they stagger - perhaps by college.
You can call Monday and ask - whoever answers the phone will be glad to share an answer. You won’t even need to give them your name. Just say you’re an applicant and you saw online someone had an answer and what should the expected timeframe be.
Honestly, I wouldn’t read anything into it. When they are ready to tell you, they will.
That someone got in and you haven’t heard is likely unrelated to whatever answer you get.
Here is last year’s Rice thread. Unfortunately, it just says March 2025 but no dates.
But it sounds like you’ll know this month - so be patient and best of luck.
