Someone tells me that on humid days, sweat that makes skin feel sticky or damp is mostly just condensation and not actually sweat. But that sounds like BS, because body temperature is almost always going to be hotter than ambient temperature, so condensation can’t form.

Yup, we are almost always going to be warmer than ambient. Which means it’s impossible for condensation to form.
The only situation in which it’s possible to form is likely…super deadly. Like…you would die within hours/minutes? (I am really struggling to find exact numbers for this duration)
Because the dew point (the temperature at which water will condese) would have to be above human body temperature. This is a function of both temperature and relative humidity. We often combine those two metric to get the “heat index” (which you have probably heard about either that or the “real feel” is another term for it.
What heat index do we need to realistically get condesation to form on a person? About 86 C (187 F) For context a heat index of 52 C (125 F) is considered an extreme danger.
