I think you may have misinterpreted what was meant by the "Most certainly use Python3 for any new projects." sentence. I don't think it's using "Most certainly" in the sense of "Most developers using Python use Python 3 for any new projects.", like you appear to be thinking it says. Rather, it appears to be saying, "Without any doubt, if you're using Python use Python 3 for any new projects." It appears to be a statement regarding the suitability of Python 3 for new projects, rather than some quantitative claim regarding the number of users of Python 3.
