Is the frequent claim that Chimpanzees have 98%+ of the same genes meaningful?

If I gave you directions from Brooklyn to The George Washington Bridge or Brooklyn to San Francisco, they’d be 98% similar as well, adding only “cross the GW bridge and keep going.” That doesn’t mean that Manhattan and San Francisco are the same place or even close to each other. We could also say a Starfish and a human have 100% of the same variety of atoms in their bodies. That doesn’t mean that a starfish will soon be writing symphonies.
