Because that's what they're documented to do.

The documentation for the sprintf function states "str = sprintf(formatSpec,A1,...,An) formats the data in arrays A1,...,An using the formatting operators specified by formatSpec and returns the resulting text in str."

The documentation for the fprintf function states "nbytes = fprintf(___) returns the number of bytes that fprintf writes, using any of the input arguments in the preceding syntaxes."
