The plasma, aka each individual particle, which would be capable of actually transfering heat, are confined by the magnetic field, confined as in literally confined to the area of space, realtive to the magnets, not "the inside of the reactor", if that makes sense, so the majority of the plasma will never hit the walls. Some of it, radiation, neutrons, or at the edges of the magnetic field, will hit the walls, that heat that's produced when they do is what we intend to use for boiling water, though I don't know the exact engineering way this is supposed to be achieved, I'm just a random smacker, but basically, essentially, yes the magnetic field avoids heat transmission by not letting the particles physically touch the other particles, and obviously, you silly, the inside of the reactor is a vacuum anyway, beacuse with air hanging around you couldn't get a clean fusion going to begin with, to adress that "empty space" thing. (Or at least I hope this makes it click into place for you.)
The reaction sustains itself by generating heat faster than it cools at a certain point, though you have to add fuel for it, which is another uncertainty on how that's going to be achieved while keeping it running. The neutrons leaving frick off out of the reactor completely. This of course creates another problem where if it runs long enough the ratio of helium to deuterium and tritium will be off and I quite frankly have NO fucking clue how they plan to get the helium out of there without stopping the machine lmao.
Inertia based confinement on the other hand works by using a small capsule of fuel that you shoot at with high energy lasers. The lasers instantly evaporate the other layer and the force created when they hit condenses the fuel to fusion ready states, then the inertia of the fuel holds it together *just* long enough for the actual fusion process to happen, but the problem with this is, this is done and works on miniscule capsules, with a total reaction time of like nanoseconds, and the capsule, as soon as the inertia can't hold the fusion anymore, blows apart completely, making it, to date, impossible to even theoretically add fuel or keep the reaction going, the goal here more to get a short burst of energy higher than what you put in.
