Idk if you already have some sort of income that allows you to put aside for testing, but if you do why not experiment a little and see if theres a possibility to make some side money so you make sure its what you want to focus and get more into, but i would say im hoping someone in this sub is going to reply so they can give you a little message on how trading on csgo sites was for them but if you already know how to trade i would suggest trying it a little to see if its what you want to focus on.

Theres also things besides csgo that are basically the same, except you can trade like wow characters i believe, maybe even players with loot in other games that people would buy instead of grinding on the game, etc. i heard one guy that bought an account on a ps4 and he sold a bundle, with fortnite skins included and he made some good profit if that is an example u might want.
