The term "ocean" depends on the context. But if the river has saltwater and is enormous, it is classified as an ocean.
A river is a body of water that flows and has a source, which can be a spring, glacier, or lake. Rivers typically flow towards an ocean, sea, or another river.

The Pacific Ocean
The source of the Tagus River is located in eastern Span. The river flows 565 miles into the Atlantic Ocean.
The mouth of a river is where it empties into another river, a lake, a sea, or an ocean.
Where a river begins is its source. It could begin at a mountain lake or as a branch of another river.
The River Niger is in Africa, its source at the Benue, and it flows into the Atlantic Ocean. There are no landmarks on the River Niger, but it is a water source for billions of people.

The start of a river is called the headwaters or source; the end of a river is called the mouth.When a river flows into another river, the 'mouth' of the river is called the confluence.
A river's place of origin is where the river begins; this is called the source. The opposite of the river's source is the mouth, or where the river ends. The mouth of the river is where the river meets the ocean.
That source may be the ocean, a lake, a river, or even aquifer.
A stream changes by joining larger bodies of water as it makes it way to the ocean. It begins at the headwaters and then into a tributary river, a river delta, and then to the ocean.
