Sources of sugar in the ketchup and salt in the seasoning cubes are both pretty helpful in survival situations. Certainly better than no food at all.

Why is it we can eat salt and drink fresh water, and that’s good for survival, but drinking water with salt in it is not good for survival?

Because salt water has a LOT of salt, and we need more water than food. Salt water is more concentrated than what our kidneys can produce so if the only liquid we're drinking has more electrolytes than we can clear shit gets out of balance fast.
