Is the word errados the same in Brazilian and European Portuguese?

Yes

The word "errados" is identical in spelling, meaning, and grammar in both Brazilian and Continental Portuguese. The only difference lies in pronunciation. In Brazilian Portuguese, vowels tend to be more "open" and clearly articulated, giving the word a more melodic and rhythmic sound. In Continental Portuguese, unstressed vowels are often "reduced" or nearly swallowed (e.g., the 'e' and 'o' may sound much shorter or more closed), which makes the word sound more clipped and consonant-heavy.
