There is a difference between the "Doctrine of Original Sin" and saying that Adam's sin affected mankind.
Christian Bible Encyclopaedia 1902
Original Sin, or native depravity, is that whereby our whole nature is disordered, and our inclinations rendered contrary to the law of God.
Understanding Catholicism by O'Gorman & Faulkner 2000
The concept of original sin helps to explain how evil can exist in a world created by a good God....
The name "original sin" did not enter into church teachings until the time of Augustine. He identified original sin as a basic yearning for self-gratification that turns people away from God....
During the Middle Ages, the interpretation shifed away from an emphasis on humans' corrupt nature to the break in the relationship with God that Adam caused by committing the first sin. Thomas Aquinas described original sin as a "weakened, disordered precondition."
Judaism’s Rejection Of Original Sin does not mean they don't think Adam's actions affected mankind. They do feel it lowered man's status, but they do not believe that man is born into this world in a state of sin.
Jews believe that man enters the world free of sin, with a soul that is pure and innocent and untainted.

The information you shared from the internet shows that Jews believe that Adam's sin affected mankind, not that every person is born sinful, which is what is implied by the "Doctrine of Original Sin."
We are equipped with good inclinations and bad inclinations and just as God told Cain.
Genesis 4:7 - Torah
Surely, if you do right, There is uplift. But if you do not do right Sin couches at the door; Its urge is toward you, Yet you can be its master.
Having a lower status does not mean born with sin.
Do you understand the difference?
There are two ways of spreading light: to be the candle or the mirror that reflects it. -Edith Wharton
