Hi Ash,I think you are correct  see here:-https://www.wordreference.com/fren/d%C3%A9duireJim

Answer

Whereas in French the verb déduire has a double meaning, in English, the two verbs "to deduct" and "to deduce" at least share a common root. The noun "deduction" still can have both meanings: to take away from something as well as to arrive at a logical conclusion.
