We really can't say for sure since we haven't seen much of other races apart from mostly Saiyans and very few Namekians, but I'd say the fact that Krillin, who got his potential unlocked by the Namekian Elder, is still apparently the strongest Earthling despite the guy not training half as much as say, Tenshinhan, might lean towards the interpretation that the Humans do have greater potential than most other races, perhaps even Saiyans, and maybe just don't have the equipment to train and harness it.
For context, the Choshinsui said to bring out a person's potential only made Goku (a Saiyan) about as strong as King Piccolo, while Krillin had a battle power of over 10,000 according to the Ginyu Force. Sure, it's a plot point, but the foundation implying Earthling Potential > Saiyan Potential is there.

It's been a while since I read that chapter, but if I recall what was said correctly, I think DBZ Macky
are right. Gohan's claim was in response to Kefla asking him about transforming, so the "growing stronger as a human" thing would refer to him not transforming at all, since humans don't have transformations, and instead just training normally. (Ultimate isn't a transformation.)
Agreed about the Gohan probably not wanting anything to do with attaining more colorful Super Saiyan forms, but it does seem that DBS treats "Ultimate" as a transformation like the video games, with only a slight difference being the presence/absence of Gohan's bang in the Anime. It'd make little sense for Gohan to not use Super Saiyan in the ToP if he can stack it on top of "Ultimate" even if he doesn't want
to when the Universe is at stake. Even Goku had mixed feelings about going SS God in the BoG Movie due to it not being his own power (at the time), yet he still went through the transformation.
