How is this different from just resizing an image larger?

A simple resize stretches existing pixels, which looks blurry past a certain point. AI upscaling reconstructs plausible new detail based on patterns the model learned from training data, producing a sharper result — though it's reconstruction, not a recovery of detail that was never captured in the original.

Will upscaling fix a very blurry or low-quality source photo?

It can improve sharpness and add detail, but there's a limit to what any upscaler can recover from a heavily degraded source — extremely blurry or low-resolution originals will show that reconstruction is doing real work, not magic.
