Looks like you are using 2.8 (and not 2.12 as indicated in your profile...).
In 2.8, the X-Y position indicator at the bottom is always an integer, and jumps on the next value when you are on the half-pixel (so "188" is really anywhere between 187.5 and 188.499...).
The coordinates on the Pointer dialog are the coordinates of the sampled pixel (so are always an integer...), so 188 is show when your cursor is anywhere between 188.0 and 188.999...)
In 2.10 things are different, the position indicator is a floating point value, so the pointer dialog always shows the "floor" of the cursor position.
