>>4371737like here let me break it down to you.
photographs you take of people in public fall under the household exemption. this is you as an individual engaging in your hobby.
you may do whatever you like to this photo, including commercial gain, as long as it does not include the personal data of individuals
now, "personal data" does not include a picture of someones face, it has to be actual data, like a passport, an ID card, a car registration plate, any sort of official documents.
so yeah, it is perfectly fine to take pictures of people in public accordingly to the EU and it is down to the individual countries to enforce their own laws regarding commercial gain and public privacy.
