I see this assertion all the time and while there is a fair bit of underreporting this line is just plain wrong but said with 100% conviction every time.
Estimates using late 2022 data assumes about 25% of Americans 16 or older have not caught COVID. 50+% believe they have not caught COVID, so unless I’m missing something drastic then if you are like me and lived as a hermit for 3+ years, followed all the reasonable precautions, and never had symptoms there is more like a ~50% chance you caught it and were asymptomatic.
