It’s common for inner pads to wear faster since that’s the side where the piston hits. There is no piston pushing the outer pad toward the rotor.
That said, you might as well remove the front wheels after safely jacking the car up and taking a look. If you don’t have the means to do that, might as well plan for front pad replacement at your favorite mechanic.
Just got rotors and pads done. When mechanic took the pads off. The inner and outer were pretty much evenly worn. Couldn't tell just looking into them with wheels off. Could've gone more. But got them done anyway. Ceramics will last awhile.
