Perhaps the search trends are more an indication of how often people shoot themselves in the foot with git and have to search for a way to unshoot their feet vs. how seldom that happens with hg. Or perhaps they're reflecting GitHub's dominance in the forge space and the fact that they only offer git, so a whole lot of people are more-or-less forced to learn something about git, so searches... Or perhaps they're reflecting something about hg users preferring other search-engines than Google... Drawing any sort of conclusive correlation between those Google search trends and actual usage or desire to use one or other distributed VCS is a fool's game.
