History tells us that Pandavas won the battle of Mahabharat, but the logical mind wonders, how come?

Look back at the warriors on the side of Pandavas and compare it to those on the side of Kauravas. Pandava army had only Arjun as warrior and he too was no comparison to the quality of warriors on the other side. Bhishma, the disciple of Lord Parshurama himself — who remained undefeated even in the battle with his own Guru, who had at his command countless divine weapons. Karna, again the disciple of Lord Parshurama, possessing the Bhargavastra of his Guru and having been declared a warrior equivalent to his Guru by the Guru himself. Dronacharya, the preceptor of the Pandavas and the Kauravas, who possessed the sword of Lord Brahma and the divine weapons of Lord Parshurama, among various divine Astras. Duryodhana, the disciple of Dronacharya and Lord Balarama and the greatest mace fighter of his generation. Two warriors in the Kaurava camp had a boon of immortality and one of death at will. All through the battle Lord Krishna keeps saving Arjun from confrontation with the main warriors till the time their weapons are exhausted. Bheem, who could slay a thousand elephants, had to break the rules of war to defeat Duryodhan and did not stand a chance in front of Dhritrashtra, because of which a statue of him was placed before the blind king to crush. At the end of the war, Lord Krishna Himself revealed to the Pandavas that Duryodhana’s army was far superior to the Pandava army. And yet the Pandavas won.
