Maybe some count spaces as words, while others don't? To a computer, even a space registers. You'll see this on Twitter where several spaces will count as characters. That might be due to the rich text editor. Or not. I'm guessing.
Try copying the whole text into a plain text editor, that won't copy over any special formatting like bold or italic, then copying that plain text into those same three word counters.
