Essentially, it's bodily homeostasis would result in an influx of freshwater into the animal's cells - because mammals, by default, have a higher concentration of solutes in their cells than a freshwater environment surrounding them would have.
However - since they are adapted to an environment that has a HIGHER solute concentration then their cells, they do NOT have the means to eliminate the excess water their cells would take up as a result of being placed in a freshwater environment - and this would eventually lead to organ failure, and subsequent death.
So yes - they would die, very slowly, very painfully - but there's your explanation WHY.

Maybe nothing. A lot of marine animals are perfectly at home in fresh water. Eels and salmon move back and forth. Dolphins inhabit some rivers. Striped bass have been introduced to freshwater lakes. Lake Nicaragua has a resident population of sharks. It depends on the animal.

Sea water is hypertonic with respect to the body fluid of marine fish. So water exits the body of marine fish through osmosis. To compensate this, marine fish have to drink a water. Marine fish evolved to excrete sodium and reabsorb water from the urine. If marine fish are put in fresh water, water enters the body of the fish. Since marine fish are equipped to reabsorb water and excrete sodium, they will not be able to expel all the water and retain enough sodium. They will eventually die.

concentration in the cells want to be a similar by means of fact the encompassing water. there's a greater robust conentration in the cells than the water so greater water will eneter the cells inflicting them to swell/probably burst becase there is way less concentration interior the clean water.

It would die. Just like if you put a freshwater fish into salt water... However there are certain species that can survive in both.

It would die from the lack of salinity (or some word like that meaning saltiness)

most marine animals can't live in that. so. .. they would probably die...

It would likely die.
