Is it possible to misinterpret a small detail that made us arrive at 13.7 billion years old that would make us be billion of years off or is it 13.7 give or take a few million for sure.

A billion years off is likely possible, given the Hubble tension. There's about a 7% difference between the present-day expansion rate favored by the CMB (~68 km/s/Mpc) and the present-day expansion rate favored by supernovae (~73 km/s/Mpc). 7% of 13.7 billion years is a billion years.
