Not necessarily. My "Supergun" was JAMMA only.
Bomb Jack is not JAMMA, so I built a converter for it. You can clearly see it in the photo. Wires go from the edge connector on the game PCB to the small green PCB that plugs into the JAMMA connector that's connected to my controls, Power Supply and monitor.
This is easy to do once you have the pinout of the game, because 90% of all 80's arcade games use the same signals, if they're not "JAMMA standard" the only difference is that the ins and outs are in different places on the edge connector. Voltages, video signals etc etc are the same. Some games need -12V (Tecmo's Silk Worm is one that I know of) but you can get that from a PC power supply as well.
Other, older non-JAMMA games share pinouts, for example my Time Pilot and Time Pilot '84 PCBs both use the "Konami classic" pinout. This means I can use the same converter for both games, and many more...if I had other Konami games from that era.
The small PCB is called a JAMMA "Fingerboard", it looks something like this:
