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

Yes

The word "dados" is identical in meaning, spelling, and grammar in both Brazilian and European Portuguese. It can refer to "dice" (plural of dado), "data/information" (plural of dado), or the past participle of the verb dar (given). The only difference is pronunciation: in European Portuguese, unstressed vowels are often more reduced or "swallowed," making the word sound more clipped, whereas in Brazilian Portuguese, the vowels are typically more open and clearly articulated.
