100 to 1 return

Need help:

Simply investing randomly is not likely to give you the 100 to 1 return.

What does "the 100 to 1 return" mean?

Thanks!

If you invest $2 in a lottery ticket and win $200 the return is 100 to 1.

Seems to me the only way you'll get that kind of return is by investing randomly and *also* getting lucky.
