The image says any cheese...
This is false.
There are two main categories of cheese, Acid and Rennet.
If the cheese is made with Rennet, it will melt, and sodium citrate will make it smooth and creamy.
If the cheese is made with acid, then it will never melt. It will burn first. Think Feta or similar.
The exception is very long aged cheeses. They don't melt all that well, even though they're made with Rennet.
Every Rennet cheese is aged, if only a few weeks, acid cheeses will spoil if aged.
