It was thought for a long time that the Sea Emperor was 1600 years old based on that data bank entry, but upon reexamination it occurred to me that everything the entry says is data that was recorded by the Precursors, meaning that the Emperor was 1600 years old when they found it.

"Comparative analysis of size and metabolic rates indicates the specimen captured by the researchers was approximately 1,600 years old. Extensive internal and external scar tissue suggest it had lived well in excess of the peak lifespan for its species"

The specimen captured was approximately 1600 years old, not is. You get this info from a terminal in the PCF, so it only contains data recorded by the precursors and the PDA wouldn't have updated the age because the PDA states on more than one occasion that the Sea Emperor is most likely dead.
