What is the error on the precision of a table obtained from a 3D plot?

Hello everyone,

I am using the method
Table= Cases[Plot, x_GraphicsComplex:>First@x, Infinity]
to obtain a table of data from a 3D-plot. For the table is used for evaluations/ calculations, I would like to know how precise such a table is / if the error on the data can in some way be approximated if I know the parameters that were used to create the plot (MaxStepFraction,…).
As I haven’t found information on this, I would like to ask if someone knows the answer.

Thank you in advance.
