Yes it is, but not all interpretations are equal. There are an infinite amount of erroneous ones, and there is one correct one. It makes absolutely no sense at all in the context of Romans 12:3 to believe God gives a measure of faith to every single individual. That's not even the point Paul is making. He's not even remotely talking about that. Observe:
I appeal to you therefore, brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship. Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect.
For by the grace given to me I say to everyone among you not to think of himself more highly than he ought to think, but to think with sober judgment, each according to the measure of faith that God has assigned. (Romans 12:1-3 ESV)'
He is obviously addressing the church in Rome. He calls them brothers, and says I say TO YOU not to think of himself more highly than he ought, but think soberly - each according to the measure of faith that God has assigned. If every single person in existence has faith, every single person in existence is justified and is going to heaven. Your refusal to be corrected here is concerning.
