Why would a compressor failure prevent a car from starting?

The car is a Nissan Versa 2017. Was told this was preventing the engine from firing. If you need any other information just ask but I am car illiterate.

compression failure. not compressor failure. The compressor is part of the air conditioning system. Compression refers to engine compression. Gasoline enginges work by pumping gas into a small chamber. That gas is ignited by a spark. The resulting explosion forces a rod to move down. Then the same thing happenes on the opposite side. The opposing rods are connected, and the opposite side rod going down makes the first rod go up. The rod going up squishes (or compresses) the gas in the little chamber so that the resulting explosion creates enough pressure to move the other rod(s). Rinse and repeat and the rods going up and down spin a big rod (crankshaft) they are all connected to. The spinning crankshaft connect to your wheels through other gears and rods and makes the wheels turn.

The amount of pressure created by the explosion in the little chamber while the rod is all the way up is compression. If something creates a leak in the chamber, such that the explosion is not creating enough pressure against the moving rod, then you lose compression. Then the engine no go no mo’.
