India dislodged Pakistan from the top following their 178-run win over New Zealand at Eden Gardens, which gave them an unassailable 2-0 lead in the three-match series.
"Our objective is to keep playing consistent cricket, having rankings and getting to number one and dropping it is not in our hands, but with this long season, it's in our control in my opinion," Kohli said at the post-match presentation ceremony.
Lauding the all-round performance by his side, Kohli said runs scored by the lower-order batsmen, spearheaded by Man of the Match Wriddhiman Saha, proved to be crucial.
"Those extra runs in the end, Saha, and Bhuvi and Shami contributing in the end, was crucial. Saha was brilliant, he's the best keeper in the country, he's doing a great job in Test cricket. That hundred in West Indies really improved his confidence, he understands how to bat with the tail now."
The India skipper also had some words of appreciation for the Eden Gardens pitch.
"Lovely Test match, a brilliant Test wicket, apart from the variable bounce here and there, it will get better and better."
Batting colleague Rohit Sharma, who top-scored in the second innings with 82, also came in for praise from Kohli.
"First innings, we understood we threw it away with a few loose shots, second innings the New Zealand bowlers really put us under pressure. Really happy for Rohit as well, stuck it out, handled the pressure really well, and you know his love affair with Eden.
"More than anything, the crowd helped us pick up those wickets today. Especially someone like Shami, running in, it makes a big difference to a bowler's mindset."
New Zealand's stand-in skipper Ross Taylor also lauded the wicket, which he said the team was not expecting.
"Very impressive, the way the bowlers got stuck in hot, humid conditions, we put India under pressure, but credit to them for withstanding it with Saha contributing in both innings," Taylor said.
"To be honest, we thought the pitch would be different. A good cricket wicket, it's just been relaid, and is going to get better and better."
India took a crucial first-innings lead of a little over hundred runs, which tilted the game in the home team's favour.
