They can tell currently whether they have enough oxygen -- but how can they determine if they still will if the pursue a squid? As I indicated, making a mistake, unlike for land predators, is a big deal.
I feel like it has something to do with the fact that the deeper down something with lungs go (in the ocean), the longer it can hold its breath due to each added atmosphere pressure on top. Something like how Free divers are able to hold their breaths for so long due to added pressure onto their lungs as they dive, I believe it’s every 30 feet deeper you go, another atmosphere is put on top.
I always thought that's so crazy considering they sleep vertically and so they have a few different atmospheres of pressure across the length of their bodies as they sleep
I am sure their are biochemical signals that get to their brain.
Also, being rather intelligent, they probably have a grasp of how much time it takes.
Is time a human thing? I don't think so, as they have done studies in dogs showing they understand the passing of time by the loss of a scent on an item.
Also Jo Nagai (great video on youtube about him) and Martha Weiss (his mentor) are making new discoveries about inherited memory. Their study is butterflies aversion to an odor, and seeing if this is inherited and not requiring "learning" it over again.
I am quite sure as this kind of work expands across species we will see that they may just be born, also, knowing what is the sweet spot.
Oxygen starvation at those depths can be extremely dangerous because at that depth, no matter how much blubber you are carting around, buoyancy won't really help you as much. They call them whale falls for a reason.

You do a lot of math when you throw a ball and/or catch one in that case.

Whales can probably feel how much Oxygen they have left and how much that is at what Pressure
I dont think their doing mental arithmetics to figure out how much they have left
They just have a very good gut feeling about how much they have

Probably how any animal judges how much ressources they have left
They make a good guess based on a lifetime of living in their body

I'll bet head-up is just the most comfy
