The purpose of ideal statements is to expose some facet of reality in isolation so that it can be understood. Where people get tripped up is in closing the loop and recognizing that the ideal is never present in isolation. It shows when they ignore details that might make their ideal less valid. They're still useful, though.

With respect, you seem to be saying that probabilities work better than absolutes, and yet your final sentence seems to be an absolute.

I am 100% sure that anything measurable exists.

Something something Sith, something something absolutes :)
