I'm not so confident we're in the top 20%. Our galaxy is middle-aged. Our star is only 4.6 billion years old in a galaxy that is 13.51 billion years.
There were several stars that blew up before we got the sun which means several systems and planets right in our neighborhood and that's just 1 star in the entire milky way.
Even at 1% the speed of light, it would take 2 million years to travel across the milky way which, relative to the age of the galaxy, is nothing.
