Although they are connected they all are different water systems. Some are fresh while others are salty. Oceans take up 70% of the earths volume while rivers only take up 0.0001%.
A lake is the smallest of the three, sea being next in size, and ocean the largest.
In 2013, the average elevation of Lake Superior was 601.71 ft (183 m). The St. Lawrence River begins at the outlet of Lake Ontario at an elevation of 74.7 m (245 ft) and flows to the Atlantic Ocean where the elevation is zero (sea level). So the difference in elevation between the Lake and the River ranges from about 357 feet to about 602 feet, depending on where on the River you measure.
yes a river can carry water from a lake to a ocean.

A lagoon is a body of water formed from the ocean leading to a beach in the round (meaning in a circle or half-circle shape). A lake is a body of water completely surrounded by land which may be fed into by a river or some such, and may feed into a river or some such.
The difference in bodies of water is usually where they are located and the type of water they contain. The difference between a sea and ocean is just that a sea is attached to an ocean and surrounded by land. A lake is usually freshwater and located in a natural depression while a river usually flows over a long distance one way.
Rivers flow into large bodies of water, such as oceans, bays, or lakes. The transition between river and ocean, bay or lake is known as a delta. Most rivers have a delta, an area where the river divides into many channels and river water mixes with sea or lake water.
