Take a photo of the blue sky. Use the largest f/stop available.

If you can see lots of black smudges in your photo, then that is likely dust on your sensor.

This is typical and to be expected with digital cameras, especially with interchangeable lenses. Some photographers get their sensor professionally cleaned periodically, like maybe once a year or more if they live in dusty areas, and many will clean the sensors themselves with either a fine nylon brush and blower or wet swabs designed especially for cleaning sensors.
