That's where you don't get it. In nasuverse you don't need to be a superhuman to qualify, just look at Jeanne. Angra Mainyu was a weakass human who worshipped as a god and he's "All of the world's evil". The key is that in Amakusa legends he got divine blessings and performed countless miracles and that is sublimed into his 2 hands NP.

As for why he is Ruler. To be one first you need to have no wish for the Grail, 2nd you need to be a Saint, 3rd you need absolute faith to the Lord. To Japanese Christians he is a Saint but he was not canonized by the Roman Catholic Church. Because of the Greater Grail's prohibition of accessing the class, Einzbern folks had to find a closest guy to be called a Saint in the east and they rolled Amakusa. who is qualifed for the rest of the conditions. He was just one step away from getting the Grail in the 3rd war but the Fate/Zero stuff happened and led to F/A.

A Ruler is not required to be super OP heroes, they act as a judge like Kirei in FSN but this time they work directly for the Grail. They are granted supreme authorities against servants summoned by the Grail to ensure its survival. If you summon Jeanne as Saber class she will be 3rd rate Saber since she's not that good with swordsmanship in life. During the events of F/A Amakusa found out the truth about 3rd magic (aka Heaven's Feel) and planned to use it to save the world so the Grail had to send Jeanne to fight him, this is why he said "Heaven's Feel, activated!" in his NP chant also.

The power of his 2 hands is very scary. Normally his NP requires too much prana to function it's impossible to utilize. In F/A he directly connected his magic circuit to the leylines to draw enough mana to create "black matter" vortex shit that acts like a black hole to suck everything into it. In FGO he has Chaldea's power plant supply, science OP.
