If your dough is too sticky add more flour
If your pie crust sticks to the rolling pan cover it with flour
If your playing cards stick to each other put them in a bag of flour and shake
Why does this work?

It’s only works on dough. The dry flour covers the sticky wet dough , making it less sticky.
For the cards hack you mentioned, it’s not a good idea because the dry flour will cover the cards and whatever sticky residue was causing the card to stick (grease,oils,) but the flour will eventual get wet and sticky itself.
It basically absorbs moisture and humidity from the objects it is spread on, drying them, thus reducing the adhesive forces created by water molecules on their surface. Also, it creates a rougher surface, so there is less contact between objects, so less adhesive force. It acts just like the chalk used by weight lifters to increase grip.
