Tapioca flour and tapioca starch are the same thing. Both are made from the cassava root that has been processed, dehydrated and finely ground to create a very fine powder. It is mainly used as a thickener in this form.
Potato starch is however different than potato flour. Potato flour is the potato, cooked, dehydrated and finely ground. It is slightly yellow or off white in colour. Potato starch is just the starch of the potato that is processed from the potato. It is very fine, white, powdery and dissolves easily. Both can be used for thickening but the results will be different, it’s the difference between using flour or cornstarch as a thickener.
Think of the diffference between potato flour and potato starch as the same as corn flour and cornstarch.
To complicate things a bit, if you come across something called “potato starch flour,” it is the same as potato starch.
