An industry is like a big group of companies and people doing the same type of work. Imagine a group of people making cars, that's the car industry. Or think about all the people making movies, that’s the movie industry. It’s like everyone in that group is playing on the same team, trying to make and sell similar things or provide the same kind of services.
Industries can be termed anything, from tech and farming to fashion and food. So, if you hear someone talking about the "tech industry" or the "food industry," they’re talking about all the businesses and workers doing tech stuff or making food.
