>or has his traning taken him as far as it possibly could?

No one has limits in DB. What allows them to keep getting stronger even after their bodies reach their limit is the accumulation and control of ki. Goku and Vegeta's bodies have already reached their limits, they can no longer strengthen their bodies or gain zenkai, but they can still get stronger thanks to ki and technique.

Saiyans just have the talent to learn and evolve with their techniques and ki In the midst of battles, all having greater potential means is that you can evolve faster. If they train anyone, including humans, can keep getting stronger as long as they're alive and even Roshi still keeps getting stronger.

Even when Gas was on the verge of death due to old age, he didn't stop evolving. What prevented him from continuing to get stronger was dying of old age because the wish to be the strongest mortal in the universe (with his talent his lifespan simply wasn't long enough to catch up with Beerus and Whis, so he could only wish to be the strongest mortal and even that was only possible because Freeza wasn't in the universe) caused him to keep losing the lifetime it would take him to reach that level. The only thing that prevented him from continuing to get stronger was that he had no time left to live.

While it's true that Daima was very shitty, it was still better than Shitper, which is even shittier.
