That's not what Romans 1 says entirely.
25They exchanged the truth of God for a lie, and worshiped and served created things rather than the Creator—who is forever praised. Amen.
It is clear the Truth was presented to them, and THEY made the decision to reject it. THAT is why they are without excuse.
Not only that, but if we go on to verse 28:
Rom 1:28 And even as they did not like to retain God in [their] knowledge,
God gave them over to a reprobate mind, to do those things which are not convenient; Rom 1:29 Being filled with all unrighteousness, fornication, wickedness, covetousness, maliciousness; full of envy, murder, debate, deceit, malignity; whisperers,
Rom 1:30 Backbiters, haters of God, despiteful, proud, boasters, inventors of evil things, disobedient to parents,
Rom 1:31 Without understanding, covenantbreakers, without natural affection, implacable, unmerciful:
Rom 1:32 Who knowing the judgment of God, that they which commit such things are worthy of death, not only do the same, but have pleasure in them that do them.
Once one goes this far in their rejection of God it seems very hard, if not impossible for them to be saved. But they have had plenty of opportunities to turn to God beforehand. So they are without excuse. But the more one rejects God's calling, the harder their heart will become, until it's too late.
