Yes it is true.

friction
Currents powered by wind are called wind-driven currents or wind-driven circulation. These currents are created by the friction between the wind and the surface of the water, causing the water to move in the direction of the wind.
the ocean surface and wind
Ocean currents are dure to a cobination of wind, the Corilis effect, and temperature differences.
Surface currents are primarily caused by the wind, which transfers its energy to the ocean's surface through friction. The rotation of the Earth also influences the direction of these currents through the Coriolis effect.
Actually charges could be created by rubbing two different insulating bodies resulting in charges at rest.These type of charges come under Electrostatics which can be also called as Frictional electricity.
Deep ocean currents are caused by 3 things:change in temperaturechange in salinity by evaporationchange in salinity by freezingBecause colder water and saltier water are more dense, they sink, and the motion causes deep currents.
If the two surfaces are moving relative to each other, then the friction between them is Kinetic Friction. Prior to the surfaces moving there was Static Friction between them.
the rougher the surface is, the more friction there will be
Surface currents are caused by the friction of wind on the water. The currents are also affected by the Coriolis Effect, which is the apparent deflection of objects moving in a straight path relative to the earth's surface.
