I'm looking for an adjective, and I'll use an example to describe what I'm looking for.
John says: "It is impossible to stand on one hand."
When in reality, it is unimaginably difficult (one might also say, statistically impossible) to stand on one hand.* John's statement isn't necessarily wrong, it's just incorrectly "rounded off" the slightest amount, and "technically correct, but not completely".
Someone pedantic could correct John, saying: "Your statement is ____."

Consider the following terms.
• unsound, “Not sound; not whole; not solid; defective”
• unsafe, in its legal sense of not being shown beyond the shadow of a doubt
• debatable, “Controversial. Not fully proved, open to debate”
• controvertible, “Open to questioning; that which can be denied, challenged, or disputed”
Use unsafe if talking with legally versed people in the UK. Use debatable if you wish to suggest the topic is open to discussion. Use controvertible if you want a simple word that is uncommon and correct: it asserts that exceptions to some assertion exist, without denying that the assertion is true of many cases.
