It forces its stomach out, and sticks it inside of the clams shell. Then with the clam inside of the stomach, the starfish puts its stomach back on its inside.
A sea star opens up a clam by attaching its hundreds of tube feet to the external surface of the shell with suction. Then, it pulls. It might have to pull for hours, or days, until the adductor muscle holding the shell firmly closed is finally weakened enough that the shell opens. Then the star fish can force its stomach in and digest the soft insides of the clam.

No, sea stars use their tube feet to pry open the clam's shell and then evert their stomach into the clam to digest its soft tissues. Without the use of tube feet, the sea star would not be able to access the clam's flesh to consume it.
The liquefied clam is then absorbed into the stomach. They feed often, and their size depends on the amount of food they eat, not on their age

A clam is a mollusk (mostly shellfish and snails).

A clam is a mollusk, along with other shellfish, and snails.
Sea stars have a unique method of eating. The animal will actually evert its stomach outside of its body and insert it into the shell of the mollusk, for example, it is prying open. The stomach will then engulf and begin to digest the prey before it is pulled back into the inside of the sea star.
The water vascular system of a sea star can generate enough force to extend and retract tube feet for movement and feeding. The force is sufficient for the sea star to grip onto prey items and surfaces. The exact amount of force generated may vary depending on the species of sea star.
