All our three kids ate everything until they were about three, after that they were really picky but it seems to get slowly better once they reach 8-9 years old. That said, when they were in daycare/kindergarten they eat what they are served. Very strange. Our oldest attended an “alternative” kindergarten where everything they were served was full of spices and herbs. She ate it all, but at home she barely touched the most plain of plainest meals. Peculiar.
My brother-in-law's children are trilingual, and they react differently depending which language you talk to them in. Because they speak French at school, if you ask them to clean up or eat their vegetables in French they do it without complaining. But do it in Polish of English, nope, not having any of it. 4 and 7 years old.
