Ping pong/table tennis

Hi all! Are there ping pong or table tennis players here? I decided that it was time to get my whole family involved in an active lifestyle, and I think that for the house this game can be great instead of watching TV (although no one will definitely refuse it). I was impressed by the benefits here https://pingpongacademy.org/benefits-of-table-tennis/ of this game and I think this game is really good.
Can someone explain to me the difference between ping pong and table tennis? Is it critical or only the rules differ?
