If it does 700 million worldwide it will make money. The reported budget is only 225 million. You usually double that for marketing and what not, so it probably only needs about 450 million to break even. Since it is a large picture with lots of marketing, to estimate on the safe side, anything over probably 550-575 million is profit.
Also, 122 million US is more than Man of Steel, which opened to 117 million. That is well behind Batman vs. Superman which was 166 million and also The Batman (Pattison's version) which was 134 million. It also topped Justice League which didn't even break 100 million, though Suicide Squad (2016 one) was 133 million. The Batman was the only DC movie since Wonder Woman in 2017 to break 100 million opening. Now they have Superman as well.
