Imo, it is a tough one for the TPG's to grade, especially if the edge looks like the rest of the card, (color/age wise) if one has been trimmed or not if it still falls into the size parameters.
(This is just my uneducated thought anyways)

In hand, it's usually pretty easy to separate a likely trim job, I think. Color of the edge itself is one of several clues. True microtrims where only a very tiny strip is cut off very modern cards (which still vary in size - a stack of 2023 Topps base are visibly different sizes if you look closely) are the ones where I just can't tell. Telling from a scan is often tough because it doesn't show most of the edge of a card.
Natural variance should lead, overall, to a roughly equal number of oversized and undersized cards.
