This is not how the narration is understood by scholars, even conservative ones.
The narration, and others similar to it, refer to the understanding that there are ultimately going to be a fixed number of people who will reach Heaven and Hell. When a quantity of 10 humans manages to reach Heaven, a quantity of 10 humans will go to Hell - this in order to fulfill that final fixed number.
Heaven bound humans will be rewarded because of their belief and good deeds and not due to the disbelievers taking the burden of their sins. Believers who have committed sins will
still have to pay their recompense in Hell, before they will be able to enter Heaven.
Similarly, individuals going to Hell is because of their disbelief and
not to save Muslims.

Does the fact that a disbeliever will be a Muslim’s ransom from the Fire mean that none of the Muslims will ever enter the Fire?Furthermore, a general principle regarding Hadith is that it cannot directly and explicitly contradict the Qur'an. If some narration appears to do so, then either the Hadith has been misunderstood or it is unreliable and therefore rejected.
On the "Jesus choosing to sacrifice himself" front, I wanted to ask, whether this sacrifice forgives
all sins of Christians or just the "original sin" of apple eating. If it is
all sins, then how could just one death be enough for all the atrocities that are committed by humans over thousands of years? And if it is just the "original sin", then why is this burden on the descendants of Adam and Eve who had
absolutely nothing to do with that sin?
