Not sure where you sourced this but its generally though hockey is the most popular in Finland, Latvia and Canada. You have Belarus and Czechia but its "football" there. And cycling in Eritrea???? Gaelic football vs football in Ireland -- pretty much tied. Handball vs football?? I'd go with football.
But that ignores Australian rules football (Aussie rules), which is the most popular sport in Australia and Nauru. In Australia we call association football soccer like they do in North America (hence our national team being called the Socceroos) so for us football/footy is Aussie rules or rugby.
