How can we sing correctly if we hear our own voice different than it actually sounds?

The difference between the actual sound of your voice and the the way you hear it is a difference in *timbre*.

Timbre is what differentiates how we perceive different sounds. It's differences in timbre that help us differentiate between the voices of two people. When you hear a piano and a guitar play the same pitch at the same volume, the difference you hear between the two sounds is also a difference in *timbre*.

Timbre is different from *pitch* which is what affects singing in tune. Because the difference in how we hear our own voice is a difference of *timbre*, and not *pitch*, it does not affect our ability to sing in tune.
