Fruit get their potassium from the soil particularly fertilised soil. Typically fertiliser consists of nitrogen, potassium and phosphorus compounds.
Common fruits that are high in potassium are bananas ?, kiwis, coconuts ? and avocados.
As Karen said, fruit gets it’s potassium (along with other minerals) from the soil that it’s grown in. Plants absorb water via their roots, and this water is rich in minerals and nutrients from the surrounding soil. The plants then produce fruit, and the minerals absorbed by the soil are built into the fruit.
