Am I correct in saying that parameters are what you define in the parenthesis when you make a new function? And an argument is what you put into the function parenthesis when you call that function later? Not sure if this right and couldn't get to the bottom of it from the video. Hope there is a simple explanation. Thanks!

Such as if you declare a function, sayHello(x,y), here x and y are two parameters and when you call this function with some value like sayHello(4,5) then 4 and 5 are arguments.

You are right.
Let's see an example:
//in function Sum, a & b are the function parameters
function Sum(a, b) {
return a + b;
}
In the below expression, when you're calling the above function, values 2 & 3 that you pass are the Sum function's arguments.
var x = Sum(2, 3);
Hope that makes it clear for you. All the best :)
