meaning - Where did the expression, "I can't win for losing" come from and what does it mean

I was thinking this expression the other day when it seemed that the odds were stacked against me.

I thought, why do I use the words, "can't win for losing"?

What it that actually mean?

Where did saying that come from and how do those words equate to "the odds are stacked against me"?

Which is a more clear-cut expression?
