No, this was never the goal. At the beginning, ITER was a science project to get the US and the USSR to collaborate on something even if the Cold War was at its height. Similar to the International Space Station. Some project with no real scientific objective, but that could spur the enthusiasm of the masses, so politicians could gain popular support while covertly pursuing a path to rapprochement.

How exactly to you get the tritium? By running some fission reactors, right? Fission reactors are a reality today, and can provide unlimited clean energy already. Why don't they? Because they are expensive? And how do we know fusion reactors, if they ever show up, will be inexpensive?
Ok, here's something else to let sink in. The best fusion reaction out there (deuterium+tritium) yields only about 5 times as much energy per kg of fuel as the fission of uranium or plutonium. Only 5 times, not 50 times or 500 times.
And of course, we don't find tritium in nature, so we need to breed it from lithium using a source of neutrons. You could use a fusion reactor as the source of neutrons (deuterium + tritium = helium + neutron), as you can read on this ITER page [1]. What that page does not tell you is that you would need 100% efficiency to be able to breed your own tritium. Good luck with that. Any deficit will need to come from fission reactors.
Somehow the dream that is sold to people is that once we get fusion reactors, we can stop using the "dirty" fission reactors. It is just a lie.
