When I subscribe to angular mat-dialog, to I need to unsubscribe it after close the dialog or in other any place? Or when the dialog is destroyed - the GC collect also its keyboard events subsribers?

    dialogRef.keydownEvents().subscribe(event => {
        // do something...
    });

No you needn't. This events are smart in Material and do unsubscribe for you.
