class CountWords implements CountWordsInterface
{
    public function execute(string $value): int
    {
        return \count(preg_split('/\s+/u', $value, null, PREG_SPLIT_NO_EMPTY));

It seems like preg_split('/\s+/u', $value, null, Sauls\Component\Helper\Operation\StringOperation\PREG_SPLIT_NO_EMPTY) can also be of type false; however, parameter $var of count() does only seem to accept Countable|array, maybe add an additional type check?
