You are correct. Modern and very helpful devices such as the enumeration of chapters and verses are not part of the original biblical text. These helpful conventions were added much later.
The setting of the biblical text into chapters occurred in the 13th century when the Catholic Archbishop of Canterbury, Stephen Langton assigned chapter numbers in order to make the reading of the Bible easier. The enumeration of the text into verses did not happen until 1551 when Robert Stephanus, a Protestant, former Catholic, classical scholar and also a printer, published the first such Bible in Paris.
