Sage chakra =/= Sage Mode. That wasnt ever stated. What he is teaching Naruto is how to enter Sage Mode.

Orochimaru and Juugo can use Sage chakra but do not use Sage Mode. Orochimaru literally cant do it and he makes Sage chakra

Fakusaku and Gamakichi are senjutsu users as well, and lack a Sage Mode

Also Slug Sage mode isnt a thing
