Not using poll data from over a decade ago may help with that: https://www.pewresearch.org/. PEW’s 2021 study found that 34% of Protestants believed only those who believed would go to Heaven though that’s largely due to 21% of Evangelicals and 31% of historically black churches: 56% of Mainline Protestants believe people who don’t believe can go Heaven.
And what individual Catholics believe doesn’t matter because Catholics aren’t Protestants; the Magisterium of the Church teaches – multiple times, stretching back to at least the beginning of the last century – that those who don’t believe are capable of going to Heaven. Anyone can believe otherwise but that’s, definitionally, not a Catholic belief (though, for the sake of completeness, it’s 68% of individual Catholics who believe non-believers can go to Heaven, as of 2021).
Again, there’s no way you can say this is true universally and, for neither Catholics nor Mainline Protestants, it’s not a minority who believe it.
EDIT: this would be the second time, in the last 2 days, someone provided updated information that I didn’t see because I was in the middle of writing a reply; looks like you found the same source as I had
