how long it will take for a map to get from pending (submission) to qualified is basically unknown, and could be anything from few hours to few years. Maybe typically few months for random average user that is capable of creating rankable maps
qualified itself is about a week (7 days min, but may be bit longer if there's a lot of maps in qualified); after that it's ranked
that being said obligatory mention that since it's your first submitted map (according to description), the likelihood of it being of high enough quality to be ranked is very slim. That's just how it is when you're starting out. Focusing on improving and getting feedback should be the priority for now
