ELI5 Wine pairings. How do chefs and restaurants know how to pair wines with certain foods?

And, more importantly, how can I learn to appreciate good wine/food combinations? What do professionals look for?

A lot of really good restaurants have a sommelier, which is a fancy name for an adult who knows everything about wines.  To do this they have to go to school, earn good grades and pass aallllll their tests regarding wine. They taste thousands of wine through a special routine, trying to find out what they taste like.

Wines get their flavors from the grapes they are made of, the length they sit in the bottle and where they are grown. Wine professionals have to find out what they taste like. With all this tasting, they then can suggest to their customers in the restaurant which wines they think the adults should enjoy. Some taste sweet and are good for dessert, some are bitter and gross which adults like with steak and some are light like water and are good with fish!

I went to school for culinary arts and had a few wine tastings and pairings with cheese! Not a professional wine person, but those who do know what they are talking about!
