I just spent fifteen minutes to corroborate the numbers for Germany, and they appear to be a vague guess by Statista. There don't appear to be any reliable stats or studies, which I find surprising; the few studies I could find had people use way less tp, eg https://www.radiohamburg.de/aktuelles/hamburg/Wie-scht-Hamburg-Gro%C3%9Fe-Studie-von-HAMBURG-WASSER-id727834.html https://www.radiohamburg.de/aktuelles/hamburg/Wie-scht-Hambu... So I'm inclined to believe the 134 is hogwash; no idea if the numbers for the US are more reliable.
