I think that the title is a bit click-baity as the Q ratio reported for the experiment is still 0.00005 (0.005 percent quoting the article).
Still an impressive achievement, but would've not used the word "groundbreaking" IMHO. I believe that in the context of nuclear fusion that word is often used to allude at reaching an energy surplus out of the reaction.
