1) The percentages you use are for all ages and all speakers (native+learned)
2) The absolute numbers don`t match with the percentages. The EU has 512.000.000 inhabitants. Thus, 33% are roughly 169.000.000, 22,4% are 115.000.000 and so on. For Polish, it would be nearly 44.000.000 speakers.
Great quiz! I'm surprised languages like Arabic are nowhere to be found. Or even some regional languages. I bet if Low German had been considered a different language, it would be on here.
