Can't find the tweet that dug a bit deeper, but basically, this difference entirely evaporates if you take a look at the GDP PPP, vs just GDP.

The EU's GDP lost about 3.1 trillion USD when the UK left. How is that accounted for?

Indeed, the article says Eurozone, while this graph (and the one on nominal GDP from same source) says 'EU'.

You don't compare GDP by PPP.

You can compare GDP per capita by PPP.
