Is it accurate to say that humans are very similar to chimpanzees because our DNA differs from that of chimps by only 1.6%?

Is it accurate to say that 9199999999 and 9.99999999 are very similar because only 10% of the characters are different?

(I will leave it to the reader to type longer stings if you want to get two strings with only a 1.6% difference in the characters.)
