Yes; you did.
Infallibility = Truth
Fallibility = Error
Nope! Fallibility only means that there is potential for error. Every time you travel anywhere, whether by car, boat, plane, bicycle or by foot, there is potential for a fatal accident, but you still move about because the vast majority of the time and for the vast majority of travelers the potential is not realized.
I am beginning to see why you make so many errors in interpretation of Scripture. Your English and Logic skills are deficient.
Peace be with you
