By and large, that is simply not so. The versions differ in a word here and a word there, but those few small differences tend to be deliberate, and critical.Catholic Bibles have 73 books, 46 in the Old Testament, and 27 in the New Testament. Protestant Bibles have 66 books with only 39 in the Old Testament. The books missing from Protestant Bibles are: Tobit, Judith, Baruch, Wisdom, Sirach, 1 and 2 Maccabees, and parts of Esther and Daniel. They are called the 'Deuterocanonicals' by Catholics and 'Apocrypha' by Protestants. Martin Luther, without any authority whatsoever, removed those seven books and placed them in an appendix during the reformation.
The reason for their removal was that Protestant beliefs could not be reconciled to Sacred Scripture and thus, the idea of Sola Scriptura would have utterly failed as a Protestant tenet. The 7 books remained in the appendix of Protestant Bibles until about 1826, and then they were removed altogether.
Some of the apocrypha are valid history, ans some are obvious, self-contradicting fiction.
None of them offer doctrine in a truthful manner.
