Games, especially multimillion dollar productions, are usually put through a testing and quality assurance process. If none of the testers exhibit motion sickness, they sell the game.
The QA testers probably don't represent older people, though. It's usually a badly paid job for younger people who already love games.
The controller vibration can be turned off in the game menu.

Tensing up might have something to do with it. Take regular pauses, stretch, have a water bottle at hand while playing, get enough fresh air. There may be a component of needing to get used to it. Don't play when tired. If you get woozy, look away from the screen for a while, look at an unmoving object so your brain can re-orient. Have enough light in the room. Increase the contrast setting of the game.
The Field of view angle (how narrow the "lens" is as you view the game) may play into it as well, but it may not be possible to change this on consoles. This is because higher FOV requires more hardware power to draw the game since more things are on the screen, and consoles may not reach playable framerates when doing that, so the developer disallows it. Which is bad.
Higher FOV (over 90 degrees) creates a fisheye effect though, and also gives the impression of even faster movement. Shooter players use this sometimes.
I will also say that movies use a narrow FOV (35mm camera = 40 degree FOV) and rarely does this affect moviegoers in a negative way... there is an element of myth to it, probably stemming from competitive first person shooter players.
Motion sickness in Minecraft or other "pixely" 3D games can happen when the brain has issues determining where the floor is / where up and down is / where the horizon is. This may have to do with the mash of pixels on the screen. It happens to me in old games like Doom and Wolfenstein - pixels, darkness, sometimes the same texture used on floor and ceiling... bad!
Try putting a lamp next to the screen, too.
