Nope. Logically, "not all fighting skills can be tested in tournaments" does not imply the statement "all fighting skills cannot be tested in tournaments." Instead, it implies that "there exist fighting skills which cannot be tested in tournaments."

In other words, it implies that some fighting skills can be tested in tournaments.
