Q:

Does the word " Humble " mean "at least" here?

I have been reading an experience told by someone about her hen. This is the sentence :

She never fully recovered (always had the limp and almost useless left leg), but died at a VERY humble 12 years old...yep...that is NOT a misprint...she was 12 years old when she died!

I wanted to know that does the word "humble" there mean "at least"?
This is the whole story:

My first hen, Emma, was "orphaned" as an adult when her keeper, who was in her 90's died. 
  She was about 3 years old when we took her in, and then she had a stroke.
  She did the same thing...would eat and lay, but couldn't walk.
  After hours and hours of me working with her and getting her to try to walk, she started being able to with a huge limp.
  She never fully recovered (always had the limp and almost useless left leg), but died at a VERY humble 12 years old...yep...that is NOT a misprint...she was 12 years old when she died!
No one believes me until I show pictures of me and Emma, with me being little holding her, then bigger, then bigger, then finally, I am an adult in the pictures...haha
Don't give up hope...a stroke doesn't always mean the end, especially for a pet hen, even when others that are "pros" are saying "it's time for the stew pot".

A:

Here, humble means :

Near the ground; not high or lofty; not pretentious or magnificent; unpretending; unassuming; as, a humble cottage. 

It is opposed to venerable age on which you should have achieved "great" things like raised a family or owned a house.
