The current (amps or milliamps) is something the load (read: device being charged) draws or pulls from the power source (charger). So in terms of the current, its true that the device is
not being "force-fed". It draws only what it needs. If the charger can't supply the current that the device demands one of two things will happen; either the charger will be damaged by the excessive demand (not likely with modern current limiting circuits in chargers) or the device will have to live with the lower current (result: slower charging).
Voltage is different. It is the electrical analog of water pressure. In terms of voltage, the device is being "force-fed". Most modern electronic devices use circuits to regulate their input voltage. If the input voltage exceeds the maximum these circuits can handle, though, the device will be damaged.
