I haven't seen any evidence so far that this thing won't stick around forever, so personally, I'd estimate anyone's chances of never being infected with SARS-COV-2 to be virtually zero.

Exposure to the virus does not automatically result in developing COVID-19 (the disease). In a healthy person, the innate immune system will neutralize the virus in the mucosal membranes of the nose.

Eventually, most everyone will be exposed. Not everyone will become sick.

However, the odds of being infected with SARS-COV-2 every 6 months forever would most likely be virtually zero.

But that's assuming all strains have the same risk.
