What are you talking about?

> These are some of the conclusions from a survey carried out online between March 27 and April 9 in the 27 member states, where 22,726 people over 15 years of age were interviewed, with a representative sample from each country. In addition to El PAÍS, the media organizations Gazeta Wyborcza, Internazionale, Ir, Kathimerini, Le Soir and Telex collaborated in the survey.

They even publish the data as well as a detailed presentation detailing number of respondents per country:

It doesn't seem too representative, that equates to less than 1k per country. Also, the age range is quite small. Still worrisome. To be frank, given recent events and geopolitical tensions, people are divided on this matter.
Accuracy depends only on sample size, not the total population size. A 1k sample gives you a 95% confidence interval [1].
