sort of. It's not really a binary yes or no on whether it's digested. Especially with seeds it's a little complicated because they have often evolved to survive digestion (especially where they spread by animals pooping them out in a physically different location than they originally grew). Some people can digest them better than others, but sprouting the seeds will cause them to morph from digestive-resistant seed form to nutrient-rich tiny plant, and make the nutrients more accessible to most people. It also (subjectively) improves the taste, which can be a nice bonus
