Almost every Dutch person does speak English, but if you get outside of the cities it’s often not very good Dutch.

I spent a few years feeling like shit because of my terrible Dutch, until my sister came to visit. My partner had a birthday party during the visit, so lots of the people I had known for years but only spoke Dutch with had to switch to English to chat with my sister. Imagine my surprise to discover that my ridiculous Dutch was better than their English!
