Same sport, same rules, same equipment. The two names come from a trademark dispute over a century old.
Ping pong and table tennis are the exact same sport. "Ping Pong" was originally a trademarked brand name; "table tennis" became the official, neutral name once the sport was formally organised internationally in 1926.
There is no rules difference, no equipment difference, and no scoring difference between the two terms - it is purely a naming history.
In the early 1900s, a British games company trademarked "Ping Pong" as a brand name for their table tennis equipment sets - the name itself was likely onomatopoeic, mimicking the sound of the ball hitting the paddle and then the table. Because it was a registered trademark, other manufacturers selling similar equipment could not legally call their product "Ping Pong", so the more generic "table tennis" grew alongside it as the practical, brand-neutral term.
Both names were in common use for decades, often depending on which company's equipment a person had grown up with.
When the sport's international governing body was founded in 1926, it needed a name that was not owned by any single company - "Ping Pong" being a private trademark made it unsuitable for an international sporting federation. "Table tennis" won out as the neutral, descriptive alternative, and it has remained the official term used in Olympic and international competition ever since.
This is exactly the same pattern seen in other sports where an early brand name eventually gave way to a generic, organisation-approved term.
Either is understood everywhere, but "table tennis" is the term used in organised, competitive and official contexts, while "ping pong" remains common in casual conversation, especially in North America. Neither is wrong - they just carry slightly different connotations of formality.
