Please don't rotate my age...

Oh man, I miss my past life when my age wasn't yet an octonian.

2 makes sense

assuming "age" means years since birth and "numbers" means digits, op would be younger than 8

I read it as days, so 2.73 years. Or months, 83.33 years.

That thing where some mothers say "oh he/she's X days/months old" for kids that are way beyond where that's relevant.

I think they're so old that humans weren't around when they were born

They said 3 numbers, not 3 digits. So, I am assuming 7, 28 and 36.

Or 627, whichever suits you.

No. The higghest age is 255, beacuse there is age overflow and human turn into being 0 age.
