Normally, a non-collapsing Ball starts at 0.50 mm pin pitch however, there could be some 0.65 mm pitch.

The pad size grows larger to accommodate the hole-in-pad annular ring.

By likelihood of the material to melt during reflow.

How I can find a BGA has collapsing or non-collapsing balls?

Not mentioned in datasheet.
