ELI5: Why is tinned tuna so cheap compared to tuna steak when they are both from the same fish?

Edit: Thank you for all the interesting responses! I didn't realise how little I knew about tuna. This is a fishy rabbit hole I'll be falling down for a while...

Typically a big tuna called albacore tuna is used for canned tuna, it's quality is low but holds up well to being fully cooked, while the higher quality fish like bluefin or yellowfin is used for steaks because people won't fully fully cook it and leave it rear to enjoy the texture, and flavor.
