Looked for that quote in the original version.
There are no references to the date of the birth of M&W, he actually
talks about him and Cyndia, here the
first and
second panel. Here's my translation (I'm not very fluent yet, if you have a better translation you're welcome to post it):
Again, the original version is less "card game centric" than the Viz translation.
So, that would make Pegasus around 24/25 years old, and he and Cyndia met when they were 10.
This version is confirmed by the Japanese version of the anime too (they
met 14 years before and she died when he was 17). In the 4Kids version,
when Yugi and co. read Pegasus diary, the flashback tells about how
they fell in love at first sight and how he was happy when she agreed to
get married, but soon after the marriage the illness hit her and she
died, while in the original version Pegasus' diary says that they were
attracted by each other and talked about their dreams: Pegasus wanted to
travel the world and become a painter, and his favorite subject was her
(synopsis of the anime taken from
yu-jyo).
