Evolution in the sense that Nudger used it the second time simply means change, but not of a specific type. All organisms are undergoing change all the time, but the change which biology terms evolution is not occurring all the time, as changes in alleles in populations only occur at the birth / conception of a new organism. Thus the two meanings of evolution are distinct and Nudger was using two different definitions of change in the same comparison.
Changes of alleles in individual organisms occur at the conception of that organism. Changes of alleles in a population are obviously on a statistical basis with many factors.
Changes in alleles is largely a non-random process (aka, natural selection). It is mutations in the germ line that are random, hence, statistical. Alleles can change somewhat due to genetic drift as long as those changes do not involve any selective pressures via natural or sexual selection.
