To get monetised you need to produce a vid every week, and get a number of followers - like 100k or so.
Then you get about 0.1 cent per view. ... So a vid you spent a day filming and two days editing for that week gets 10,000 views - you get $1.
The only people who make enough money to justify it as a hobby have a million or so followers, pump out two vids per week and get 100k views per vid.
