That's exactly how I meant it too. Assuming SpaceX doesn't go belly up in the next 10 years while developing Mars rockets, then we may see his, and many others, dream come true in our lifetimes.
A trip to another star system is out of the question for at least a century or more. Probably out of the equation for anyone currently alive. The tyranny of the rocket equation is too difficult to get around. We will either need some incredible new physics(something like the EM drive but actually works), or many many years to create a space based industrial capacity that is required to build the massive ships that will be required.
