The first one is incorrect because a negative verb calls for an object in genitive. Here are a few more examples:
Ji turi sūnų
. Ji ne
The second one doesn't sound natural without any context. When you use the accusative, it seems as if you're saying The next person wants to win the books
in English which sounds just as strange because it implies you are talking about a specific quantity of books (which in turn implies you're talking about some specific books).
I believe you were trying to say something along the lines of The next person wants to win (some) books
where it is not the books that have the focus but rather the fact of winning them. In that case you would want to use the genitive, as in my correction. Using genitive implies undefined quantity thus removing focus from the object of the verb.
Back to the game. My answer followed by the next statement.
Ne, nenoriu laimėti, nes kol kas man jų nereikia (o kai labai prireiks - tiesiog nusipirksiu).
Kitas žmogus ateinantiems metams turi svarbių planų.
