Is this already an already balanced chemical equation, or am I blind lol?

You have a hydrogen on one side and two one the other. It is not balanced.
 
this is not balanced because there are two H in the products and one the the reactants, so to balance it you:
1st.) put a two in front of HCl ~ Zn + 2HCl --> ZnCl + H2
2nd.) then you need another two in front of the ZnCl~ Zn + 2HCl --> 2 ZnCl + H2
3rd.) Then you put a 2 in front of the Zn~ 2Zn + 2HCl --> 2 ZnCl +H2
*Now it's balanced :) let me know if you have any questions*
