Did not say whether the figures in the paper are Chinese or English. The numbers in the paper are counted as characters, not words. Enter statistics in the bottom corner of word, and the meeting will be very detailed, such as words, characters, spaces and so on. You will see that numbers are not words, but characters.

The number of words in a paper depends on the number of words.

The definition of characters is that characters are the general name of letters, numbers and symbols in electronic computers or radio communication. It is the smallest data access unit in the data structure, and usually a character is represented by eight binary bits (one byte).

I hope my answer can bring you some help or reference!
