Gerrard became the 24th player in Premier League history to score 100 goals in the competition when he struck from the penalty spot shortly before the interval at St James' Park.
But the Anfield skipper, who follows in the footsteps of Merseyside duo Robbie Fowler and Michael Owen, would rather have seen Brendan Rodgers' men go on to take all three points.
Gerrard's penalty cancelled out Yohan Cabaye's long-range opener and came after Mapou Yanga-Mbiwa saw red for pulling back Luis Suarez, but the Magpies went back in front through Paul Dummett and Liverpool needed a second-half leveller from Daniel Sturridge.
"It's a good milestone for me and a great personal achievement," Gerrard told the club's official website. "But I'd certainly swap the goal for two extra points today, that's for sure.
"Points for the team and where we finish in the league are my priority. If personal milestones get crossed off along the way, then great.
"I thought Newcastle started the game a lot better and brighter than us, and probably deserved to go a goal in front.
"The sending-off completely changed the game, we took control from there and deserved to take the three points, but we couldn't get that final goal.
"Our attitude improved when they had the man sent off. We did everything we could to win the game. Unfortunately we have been caught out with a set-piece.
"From the sending-off we were brilliant. We played some really good stuff but, frustratingly for us, it wasn't enough."
Gerrard captained England to victory over Poland in midweek which secured their place at the 2014 World Cup, and admits victory at St James' Park would have capped a dream seven days.
"If we had got the win today, it would have been the perfect week," he added. "The week has gone really well from an international point of view, and getting the goal here was fantastic.
"But I always search for perfection so I'm sadly a little bit down that we haven't taken maximum points."
