Pablo said that sports taught him to follow instructions, prepare for games, adjust to new situations, and the value of losing as well as winning. Where is the error

And the value of losing as well as winning is the error.

Explanation:

That phrase is wrong because it breaks the parallelism in the sentence. Parallelism means that the same form of a word or phrase is used throughout a sentence; for example, only gerunds or participles are used.

In the sentence above, infinitive phrases are used: to follow instructions, prepare for games, adjust to new situations, and then suddenly a noun is used instead of another infinitive phrase.

The correct sentence would be ... and to value losing as well as winning.
