Are all people without distinction justified in the same way?

Yes. In Romans 3:29–30 Paul once again returns to the issue of the universality of the gospel (cf. Romans 3:3, Romans 3:22–24). He does this by a rhetorical question: Or is God the God of the Jews only? Is he not the God of Gentiles also? The answer is obvious, for we are speaking of the Creator of heaven and earth: Yes, of Gentiles also, since God is one. For this reason he also opens up one path of reconciliation to all, for he is the One who will justify the circumcised by faith and the uncircumcised through faith. Paul’s readers have come to obedience of faith in God and can attest from experience that God is the God of all the nations of the world. The one God now indeed justifies Jews and Greeks through the power of faith. The reality of the gospel has, following Pentecost, become evident though the work of the Spirit. This gospel does not demand that people first exchange the works of idols for the works of the law before the Spirit of Christ could be poured out. The origins of the Gentile Christians, also in Rome, is revealing for everyone, including the Jews.¹
