No. Not really. It's certently possible to do in 1 day. However, the only catch is that you need to win games. Since that is by far the fastest (sorta the only) way to get real amounts of points.
(1 day may be a bit out of reach. But as an example of fast leveling https://www.warzone.com/Profile?p=75100331239

Completed 337 ranked games (218 wins/ 337)
Levels gets exponentially harder to get too btw. As the levels link below shows.
If you win 300 ~ 500 games you should be level 47 I think?
Also, different games have different multiplier. https://www.warzone.com/wiki/Points
