No difference! Can use either word in any sentence.
I think both words can sound a little odd in some sentences though. Perhaps there is a connotation of continuous action when we use "until" whereas "till" fits fine with both continuous actions and with something that has a fixed time associated to it. Like "It ain't over till the fat lady sings". "Until" might look odd there, as the "getting over" happens at a point in time - the singing of the fat lady. Till or Until would feel okay for "It goes on until the fat lady sings". I believe there are also instances when "till" would look odd. May be "till" is less preferred as a starting word in a sentence. Like "Until I finished writing, I had no sense of time" might look odd with "Till" at the start. But these are generally only minute stylistic differences. I don't think anything is considered wrong as per the rules of grammar; both words are listed as fully interchangeable.
