Actually there are still people and some countries that are not really aware of Bitcoin. For example, in my country it is not so popular especially among people who are over 45 years old. Before I started hang out with other crypto enthusiasts, I had thought that there were just no people who were interested in Bitcoin. But personally I am crazy about Bitcoin and consider it to be infinity as well, as its technologies can't spoil.
Approximately 1% of world population are Bitcoin users according to many estimates and those who are aware of them but do not use them,,, if we want to use 6 degrees of separation rule, then we can even say half of the world (not including children) already know about Bitcoin.
But as to what knowledge they have and the accuracy of it, judging from people even on this forum,,, I wonder if 1% of those who know about it know it with enough accuracy
