Most have not yet had it; whenever Covid 19 is given a chance - particularly inside with lots of vocal activity - it takes it. The idea that more must have had it is widespread, but I think its proponents under estimate the changes that most people have made to reduce their risk - partly voluntary, partly imposed.

I know the WHO have got a lot wrong, but I think their most recent report was about right.

Do remember - people without symptoms can and do spread it; 2 metres is better than 1 metre - 5 metres is better still; mixing with others inside is much riskier than doing so outside.
Not sure if I'm understanding what you're saying in your first point.

According to the Swedish study

“Moreover, roughly 30 per cent of the blood donors who’d given blood in May 2020 had COVID-19-specific T cells, a figure that’s much higher than previous antibody tests have shown.”

So these are all people who had been in contact with the virus.

I suspect that you're right when you say that the majority have not had the virus (although they may have in some of the early hot spots like New York). But I'm open to the possibility that a lot more have had it than official estimates suggest based on antibody tests alone.
