Orochimaru copied Kabuto's skills and knowledge when he took back his chakra from him https://naruto.fandom.com/wiki/Orochimaru#Chakra_and_Physical_Prowess. Not to mention Kabuto's DNA as part of his now thanks to Jugo and Sasuke and Oro has Wood Release and Hashirama's healing ability combined with his own healing abilities. Oro is Kabuto but better now and I think its safe to say he's hiding his abilities and is def 3rd Strongest right now.
