A business can be EBITDA positive but cashflow negative, or vice versa. However healthly your margin is, it is game over if you are unable to service your debts (including employee salary) before you receive cash from customers/investors.

On the other hand, if you are operating at a loss, you will be able to continue doing so indefinitely via continuous cash infusion by investors (which might include the public in case of a public company)... until the cash does run out.
