T-cell tests are what show the true number of people were infected.

T-cells are the first line of defence and a huge number of people are able to handle covid with T-cells alone, but the next step is antibodies.

T-cells have been shown to be responsive to SARS 17 years on, whereas covid antibodies have a 36 day half-life.

T-cell studies showed that huge numbers of people have had covid and didn't even notice. This means the IFR (Infection fatality rate) is tiny, less than 0.0013.

This is the best approach of measuring total infected by covid. Your suggestion, that even fewer people have had it is somewhat substantiated by false positives related to PCR cycles, but you are ignoring other means of confirming a positive covid case. And this causes a much higher IFR, meaning measures to combat it are even more justified.

Where false positives do play a role, is that they artificially increase the death toll, but this is due to definition of a covid death. If someone dies of a heart attack, do a covid test, get a false positive, caulk it up to covid, not heart disease.
