Using the laws of operations can sometimes simplify calculations. For example, $1: -2+5-6+17=-2-6+5+17=-8+22=14$; $2: 99\times 99=99\times \left(100-1\right)=9900-99=9801$; Please refer to the examples above and simplify the calculations using the laws of operations:  
$(1) -2.48+4.33+\left(-7.52\right)+\left(-4.33\right)$;  
$(2) \frac{7}{13} \times (-9)+\frac{7}{13} \times (-18)+\frac{7}{13}$;  
$(3) -20\frac{1}{19} \times 38$.
