When you say "emphasis on" you mean the single mention with no distinction between that stat and the any other of the facts of the case? I don't think they really put any weight on if that's a lot or not.

Personally I would say it is a lot. No other number mentioned in the article even approaches a billion. Billions are big. It might be not be true big data big, but it is still a lot of customer records for a migration project (depending on what exactly they were trying to do within the migration) and it does illustrate why they had so many issues, because there was a lot to deal with.
