eli5 how Google claims not to 'sell' your data, so what does Google do to give data to others, and what data is being shown to them?

Google does not directly give your data to anyone. They don't want to- access to your data is the secret sauce that makes Google ads more valuable than ads from other places.

Instead, companies can come to them with an advertisement targeted towards men in their 30s in the American Southeast that like baking, and they can make sure to show that advertisement to that group of people. Since they're only showing the ads to the people most likely to respond to them, they get more responses and so Google gets more money from the advertiser, while being able to sell ad spots for other demographics to other companies.
