I can’t say for sure. Nobody really can but there is a divide in some protestant faiths that someone “once saved is always saved.”. Meaning that if you ever believed then you’re good to go. I think this idea is rooted in John 10:28-29 ESV [28] I give them eternal life, and they will never perish, and no one will snatch them out of my hand. [29] My Father, who has given them to me,is greater than all, and no one is able to snatch them out of the Father’s hand.

A lot of Christian faiths don’t agree with that logic though.

I think largely though people believe Romans 2 only applies to people who have never heard.
