That’s not really true. Nuclear pulse propulsion technologies that could take us to low single digit % of light speed are feasible in the next 10-20 years.

It's estimated that Earth-like planets around sun-like stars are an average of 20 light years apart. Covering that distance at 0.01c takes 2,000 years.

Never said 1% of the speed of light and the post was about interstellar travel. Alpha Centauri is 4.3 light years away.
