How long would it take to learn to make decent 3d models?

I'm a programmer who would like to make games in my spare time as a hobby.

I have zero 3d modeling experience. If I only have like 1 hour a day to spare learning 3d modeling, how long would it take me to get good enough to make decent-looking models (just cartoonish things, not hyper-realistic ones) that could be used in a presentable game? https://tweakbox.mobi/ https://getappvalley.com/ https://vlc.onl/

Is even that goal too ambitious for this level of time commitment and I shouldn't bother? How many months/years would you estimate it would take?

my issue got solved!!

Amazing work!! Keep it up! Many congrats!
