The 33-year-old's top-flight tally reached triple figures on Saturday afternoon when he found the net from the penalty spot in his side's 2-2 draw at Newcastle United.
"Everyone has been speaking about it for a while," he told BBC Sport. "I would have liked to have got it from open play, but I will settle for a penalty.
"I remember my first one against Sheffield Wednesday [in 1999] when I went past Des Walker and slotted it away. Your career goes so quick that you have got to cherish every moment."
Gerrard, who has now made 449 league appearances, is the 24th player to score a ton of Premier League goals.
