Does the Almighty's saying, "Indeed, Allah does not forgive association with Him, but He forgives what is less than that to whom He wills," include one who believes in the oneness of Allah and associates nothing with Him?

One must believe in Allah, in His Prophet Muhammad (peace be upon him), in the prophets who preceded him, and in the rest of the pillars of faith. Whoever does not believe in some of these is among the people of Hellfire. And whoever hears of the Prophet (peace be upon him) and does not believe in him and follow him, his claim of monotheism will not benefit him, and he will be among the people of Hellfire, due to the saying of the Prophet (peace be upon him): "By Him in Whose Hand is the soul of Muhammad, there is none among this nation, whether a Jew or a Christian, who hears of me and dies without believing in that with which I have been sent, but will be among the people of the Fire." And due to the saying of Allah the Almighty: "Indeed, those who disbelieve in Allah and His messengers and wish to differentiate between Allah and His messengers and say, 'We believe in some and disbelieve in others,' and wish to adopt a way in between – those are the disbelievers, truly. And We have prepared for the disbelievers a humiliating torment."
