I am not sure it is quite that simple. Some people have these abilities but they still must be developed. For most it would not be possible to throw similarly well with either hand. But for those for whom it is possible, the rod bility must still be developed through practice.I see that some were forced to be ambidextrous. I am right handed but due to injuries and such, I was forced to develop many usages for left hand. I am not sure playing some sports with different hand makes one ambidextrous. IMO, if one can do most things equally well with either hand, that makes one truly ambidextrous. I've got some ways to go.

When I type I'm ambidextrous
I use both hands for various distinct things, so not truly ambidextrous as it's awkward to switch to the other hand for the same task.
I have noticed especially for eating some people only use 1 hand, so they:
put knife in right hand.
cut food.
put fork in right hand and eat.
Then repeat.
It's so much easier to keep the knife in 1 hand and the fork in the other and eat.
If you have a dominant left eye and are right handed there would be issues doing certain things, right?
When it comes to cutting and eating food, I suspect what you are describing in most cases is etiquette, not a different ability.
