Spurs were comprehensively beaten by their North London rivals with goals from Per Mertesacker, Lukas Podolski, Olivier Giroud, Santi Cazorla and Walcott cancelling out strikes from Emmanuel Adebayor and Gareth Bale.
The attacking edge shown by Arsenal in the game was a far cry from their recent toothless displays up front, and Walcott is delighted that the Gunners have rediscovered their scoring touch.
"I think the better team won," Walcott was quoted as saying by the official Arsenal website.
"They did have some good patches but in the grand scheme of things I think we deserved to win.
"We were very ruthless going forward and had five different goalscorers, which hasn't happened for a while.
"It's funny that it's the same scoreline as last year - who would have thought that?"
Arsenal have a tricky run of games which may define their season coming up next; clashes against Montpellier, Everton and Aston Villa promise to give the Gunners a stern test and Walcott believes that the win over Spurs will have given them the necessary boost to win their following games.
"It has been up and down [this season]," Walcott mused.
"I am starting to get back into the team, and we have people like Santi Cazorla who has shone in his first season in England.
"Olivier Giroud is starting to show what he can do, Lukas Podolski is getting goals which is very useful and we have Jack [Wilshere] back.
"I think the confidence has always been there. But this was a massive win for us."
Defender Bacary Sagna echoed his Arsenal teammate's opinions and added that the Gunners would continue to focus only on the next game ahead.
"It's very important. We want to stick to the top. From now on, we just need to keep focused, look forward and win game by game.
"It was amazing to play. It's always a great pleasure to play [in] a derby, especially when you win.
"It's just great. We managed to score many goals."
Arsenal are currently sixth in the Premier League on 19 points, two points ahead of Spurs, who are in eighth position.
