In navigation, the course of a watercraft or aircraft is the cardinal direction in which the craft is to be steered. The course is to be distinguished from the heading, which is the compass direction in which the craft's bow or nose is pointed.
True heading is your direction relative to true north, or the geographic north pole. The difference is due to the magnetic north pole and geographic north pole being hundreds of miles apart.

So let's let's do the arithmetic
The direction in which the longitudinal axis of an aircraft is pointed, usually expressed in degrees from North (true, magnetic, compass or grid). ( Source: ICAO) Track.
True course: the course corrected for compass errors and plotted in the chart, tc and is equal to Course Over Ground (COG) or Course Made Good (CMG) . Compass course: (cc or CTS) the course which is corrected for both variation and deviation. Magnetic course: (mc) the course which is only corrected for variation.
A ship's true course is determined by the direction from the ship to the geographic north pole (also called true north). Navigation charts andthe compass are labeled with true north, but setting a ship's course is not merely a matter of steering in relation to the north pole.
Since the beginning of flight, pilots have been using the magnetic compass for navigation. It doesn't matter if you're flying a Piper Cub or a Boeing 747, you'll find a magnetic compass in the cockpits of almost any aircraft.
Simply put, no. According to the FAA's Instrument Procedures Handbook (1-42), "runway heading is the magnetic direction that corresponds with the runway centerline extended (charted on the airport diagram), not the numbers painted on the runway.
Why is the heading on my magnetic compass different from the heading on my GPS? The reason for the discrepancy between the heading you are reading from the magnetic compass and the "heading" on the GPS is that the GPS does not receive magnetic heading input. Instead, the GPS will display ground track.
Heading is the direction the aircraft is pointing. The aircraft may be drifting a little or a lot due to a crosswind. Bearing is the angle in degrees (clockwise) between North and the direction to the destination or nav aid.
The heading of an aircraft, which is also referred to as bearing or vector, according to NASA, is the direction the aircraft is pointed in. For pilots, direction is always expressed in relation to due north on a compass and measured clockwise. Hence, north is 360 degrees, east is 90 degrees and south is 180 degrees.
In navigation, the heading of a vessel or aircraft is the compass direction in which the craft's bow or nose is pointed. Note that the heading may not necessarily be the direction that the vehicle actually travels, which is known as its course or track.
