Dealer says breaks are fine

I bought a brand-new Kia Forte last year and have driven it for 50,000 miles. Over the past couple of weeks, I started hearing a squishy noise from the brakes, so I assumed the brake pads needed to be replaced. Today, I took the car to the dealer for a maintenance check, and they told me the brake pads are at 7/10 and still have a lot of life left. I’ve read online that brake pads usually last around 50,000 miles on average, but 7/10 seems too good to be true to me! Can anyone with a Kia confirm if the pads can last more than 50,000 miles?
