Roughly speaking, yes.

Raster data consists of samples taken at regular points. In the case of raster images, the samples are some sort of quantification of colour.

Vector data consists of an abstract description of shapes and their properties. Again, in the case of the images, the primary property would be quantified colour.

"More abstract" would be a reasonable way to describe vector data, but I'm not even sure how it would be meaningful to compare "mathematicalness" as it were.
