Yeah, but the Sun only works because of its unfathomably massive size, compared to anything we can do on Earth. If you take 800 cubic meters of plasma from the core of the Sun, about the same volume as ITER, it only produces 216 kW - comparable to the engine in your car. And in that volume, you will have an average rate of 1500 hydrogen fusion reactions per second. Compared to ITER, this is something like twelve orders of magnitude slower. That is why ITER needs to go to much higher temperatures than the sun.
