Quite frankly I have no idea who she is. Perhaps I’m just too uncool.
Limited atonement? I think all churches have some such doctrine. Did Jesus really die for everyone (universalism) or those who are saved, whether though classical Augustinian thought or somewhere on an Arminian scale.
On the one hand, "God's grace has been revealed, and has made salvation possible for the whole human race. (Titus 2)"
and on the other hand,
"But he that shall endure unto the end, the same shall be saved" (Matthew 24:13)
In other words, Christ truly is the Savior of Mankind, and died for the salvation of the World --- those are universally inclusive terms --- but we must enter and remain in a saving relationship with Him.
But I think no one can say ---as Patti Smith said 40 years ago, "Jesus died for someone's sins, but not mine." Perhaps she thinks she was predestined to be lost, which is (I think) a tenet of Calvinism, but in Catholicism would be called the sin of Despair.
But as I said before, I may be wrong about Calvinism. I refrain generally from commenting on Calvinst doctrine, since I don't know anything about it. really.
