Why is it called a non for profit charity when the people running it are taking million dollar salaries?

"Nonprofit" does not mean "no money" dear.

It's an accounting term.

The non-profit designation means that the government allowed them that designation because of the type of business they are conducting.  That designation means that they do not have to pay taxes.  Of course they are in business for profit.  Where do you think they are getting money to pay employees, buy supplies, and support themselves?

Because those are salaries, not profits. Salaries go to workers. Profits go to owners.

Because when you're hiring someone to manage an organization with a budget of 4 billion dollars a year you really want someone who is qualified, experienced and will deliver results.

Hire someone incompetent, kiss that 4 billion goodbye.

There are very few charitable organizations that pay an Executive Director 1 mil.  

Only the biggest few do, and they do huge jobs. The charity itself is non-profit. That doesn't mean the employees work for free.

probably cause its for charity

Because the charity

the corporation

is a legal entity

and

that legal entity

does not show a profit

even though employees of the corporation are paid by the corporation

sometimes (quite frequently) extremely well-paid at the highest levels.

Note that

for the corporation

salaries are an EXPENSE

the OPPOSITE of profit.
