"Oh you want to to serve ads to individuals that shop at Uniqlo? Here's a list of profiles to target that have checked into a Uniqlo three times in the past 6 weeks"

No, this is not true. It's more like "Oh you want to to serve ads to individuals that shop at Uniqlo? Give us your ad creative and we will show you to the profiles that have checked into a Uniqlo three times in the past 6 weeks"

Additionally, at FB ads, often it's custom audience, and in that case it's "Oh you want to to serve ads to individuals that shop at Uniqlo? Give us your ad creative and list of email addresses of people you want to target and we show them your ads." (though you can actually do "similar audience" and so on.
