Estimates of "# of searches Google serves" are always fascinating to me. I don't see statisticbrain.com publishing a source for their estimate, although maybe I'm just missing something.
AFAIK, Google doesn't really publish a precise number. They often say things like "Over a billion searches a day". But then they keep that published estimate the same for years during which growth is obviously happening. At some point, they'll publish a step function upgrade to the estimate.
Of the top of my head 2 trillion searches sounds reasonable but I think there is a lot of fudge factor in that guess.
