Does the only difference between using throw and throws is the English grammer?

No, "throws" is used in method declarations, as in
void foo() throws SomeException {}
whereas "throw" is used to actually do throw an Exception, as in
throw new SomeException();

I.e. "throws" is just a warning, meaning "this method may throw the following exception". While "throw" is a command - "throw an exception right now".

"throws" is just like try-catch statement
Excepiton may happen
"throw" means that the exception throws
