Did Nebuchadnezzar, the king of Babylon really worship the God of the Hebrews in the book of Daniel?

After Jehovah restored Nebuchadzezzar to his senses after seven years, the king praised Jehovah, saying: "Now I, Nebuchadnezzar, am praising and exalting and glorifying the King of the heavens, because all his works are truth and his ways are justice." (Dan. 4:37) Still, Nebuchadnezzar never became an actual worshipper of Jehovah.
