The iPhone doesn't have a particularly large market share in the EU, it's just not that popular. "Europe" also includes other nations and regions, eg. the UK and the Middle East. Many of those nations also feature the iPhone having a large market share, despite them potentially being a "poorer" nation.
The UK, Russia, Saudi Arabia, etc all have larger iPhone penetration in their population. The UK + Russia + Saudi have a similar collective population to Germany, France, and Italy, but each also feature a higher iPhone usage per capita than the EU.
So I think it stands to reason that the EU probably features heavily in that number, but is certainly closer to half of it.
I think that's a big assumption.
