Raw starch granules resist digestion, e.g., raw bananas, raw potatoes. This does not depend on the amylose or amylopectin content, but rather the structure of the granule protecting the starch. When starch granules are cooked, water is absorbed into the granule causing swelling and increased size.
As for potatoes being a high-glycemic food, while this is true, Palinski-Wade says that eating a potato doesn’t necessarily mean you’ll experience changes in energy levels or mood.

For example, boiling potatoes reduces the α-chaconine and α-solanine levels by only 3.5% and 1.2% respectively, but microwaving potatoes reduces the alkaloid content by 15%. [23]
To extract the starch, the potatoes are crushed, and the starch grains are released from the destroyed cells. The starch is then left to settle out of solution or separated by hydrocyclones, then dried to powder. Potato starch contains typical large oval spherical granules ranging in size from 5 to 100 μm. Potato starch is a refined starch ...

About 30% of starch is hydrolyzed into disaccharide in the oral cavity (mouth).
