The terms "soccer" and "football" are often used to refer to the same sport, but usage can vary by region.
In the United States and Canada, the sport played with a round ball where players mainly use their feet to control the ball and score goals is commonly called "soccer".
In most other parts of the world, especially in Europe, South America, Africa, Asia, and Australia, the same sport is typically called "football". In these regions, the term "soccer" is less common, although it may be understood.
There are also other sports that are sometimes called "football" in different regions, such as American football (played in the United States and Canada, with a different ball and rules) and Australian rules football (played in Australia), but when the context is clear, "football" usually refers to the sport known as soccer in the US.
So, when people say "a soccer" or "a football" in the context of the sport played with a round ball and primarily using the feet, they are generally referring to the same sport, just using different terms depending on where they are from.
So, the answer is it can be either depending on the region's usage of the terms.
