Yes, based on the Gregorian calendar the 3rd millennium started in 2001.
However the popular sentiment doesn't follow the technical convention. Popular convention refers to 1980~1989 as 80s, 1990~1999 as 90s, and 2000~2009 as rolling to the 0ties - in our popular convention 2000 is a new century and new millennium.
Basically there's no agreement here. The 0001-based Gregorian calendar definition is correct, but people ignore it and follow the popular 0000-based convention since it's simpler, lines up with bow we now think of decades, and doesn't really make an iota of difference.
