"Soccer" is a British word in origin. It is one of those words which has gone out of use in its home country, and stayed in use elsewhere.
Non-Brits will probably not reailse that there are class-warfare overtones in this.
Of the two English football codes, Association football tended to be a sport with working-class interest, while Rugby Football tended to be of more
interest to the upper classes, who played it in their "public schools".
But the two abbreviations, "Soccer" and "Rugger" were both given by the upper classes (the "er" ending gives it away.)
So "Soccer" was a working-class sport with a non-working-class nickname.
One of the effects of the Sixties in Britain was that the upper classes lost their influence over popular culture, which became more working class.
This was fatal for the use of the word "soccer".
As far as the working class was concerned, the national sport, soccer, had always been called "football". If this sport alone was being called
"football", the word "soccer" itself was redundant, and stopped being used.
However, other countries continue to borrow words like "futball" or "socero" quite indifferently, completely oblivious to the social overtones of
these words in their native country.
Especially, of course, countries like America or Australia who have native "football" codes of their own, and need a separate word for "soccer" to
