What it does say is
1. Israel must do more to prevent the possibility of genocide. Genocide is killing a people with the intent of killing them for the sake of destroying them, and not as collateral damage, so it does not mean stopping all death. Collateral damage, unfortunately, remains on the table.
2. Israel must report back in a month with how they are doing that. For example, they could show lower amounts of collateral damage, an increase in aid, punishments for officials that make statements that could be construed as genocidal, and so forth.
That is better than nothing, to be certain, but it is far from a ceasefire, unfortunately.
I think there was a miscommunication. You said that the provisional measures said that Israel must stop killing Palestinians, and so there is no way to have a ceasefire. I was saying that what's actually in the provisional measures is a reiteration of the Genocide Convention, of which all countries must already abide, including Israel. Whether or not it's likely a country is commiting genocide or it's self defense, they haven't ruled on. I deliberately avoided any speculation with my comments.
The court said no such thing.
