Does the addition of a second “some” change the meaning of the following sentence?

I’d like know to whether the following sentence retains its nuance and meaning with the addition of “some” before the word “others”.

“I’m good at some types of art and bad at others.”

“I’m good at some types of art and bad at some others”

The difference is in the amount of implied art types that the person could be bad at (or neither good nor bad at, if you look at it another way).

“I’m good at some types of art and bad at others.”

This sentence says that you are good at some art types and bad at either some of the others or all of the others. If you said, "I’m good at some types of art and bad at the others." then that would mean that you are definitely bad at all the other types of art.

“I’m good at some types of art and bad at some others”

This sentence says that you are good at some art types and only bad at some of the others, meaning there are definitely some art types that you are neither good nor bad at. This sentence feels as if there could be some importance to the art types that you are neither good nor bad at.
