To answer the question you have to look at the source:
Induced dragInduced drag is a drag type which appears on wings with finite span. The polars given are for a 2D profile section and therefore without induced drag.
What about the parasitic drag? Using Wikipedia's definition only skin friction and form drag are taken into account. Interference drag, which is a 3D drag type dependent on the position of other bodies, can't be included either.
