- There's almost sixty million native speakers in Italy itself and the Italian-speaking part of Switzerland.
- Italian remains a prestige language spoken as a second language by a good number of Slovenes, Croatians and Albanians.
- Many Spaniards and Romanians speak Italian as a second language, at least partly because the similarity to their own native languages makes it easy to learn.
- There's a large Italian diaspora in other European countries, notably France, Britain and Germany, where Italian is still spoken at home.

There's also more than 150k Samoan speakers between the two countries, and if we assume that the vast majority of people in Samoa/American Samoa speak Samoan too, there's probably also something like 400k speakers of Samoan in Oceania
Australian 2021 census data is summed up well at https://profile.id.com.au/australia/language (language spoken at home) and New Zealand 2018 census data is summed up well at https://www.ethniccommunities.govt.nz/resources/our-languages-o-tatou-reo/languages-in-nz/

I see you placed Arabic in #5 for Asia with 100 million speakers.
