Strictly speaking, no, they are in PostScript basic units, and
PostScript basic units default to 1/72 of an inch, see the

  PostScript language reference manual,
  Adobe Systems Inc. - 3rd edition,
  Addison-Wesley, Reading 1999
  Section 4.3.1, page 183

together with

  PostScript Language Document Structuring Conventions Specification
  Version 3.0, 25 September 1992, Adobe Systems Inc.,
  Section 6.1, page 94

For practical purposes, "point" can often be used as a synonym for
"PostScript basic unit", but that is imprecise terminology and may
cause confusion.
