Is the precision of a gage the same as its resolution?

No. Precision is different from resolution, just as accuracy is. The resolution of a gage is the degree to which the output of measurement can be broken down, whether in decimal places, parts, divisions, or counts. Precision relates to the resolution, but takes it a step further. The precision of a gage is the smallest (resolution), true (accuracy) measurement that can be taken repeatedly and reliably. The more precise a gage is, the greater its ability to take finely-tuned and accurate measurements again and again. While a gage might take the perfect measurement once, what you really want is to be confident that the gage will take as close to the perfect measurement as possible, every time—this is precision.
