It’s easy to fall into the rabbit-hole of ‘improvements’ to a cheap bass, but unless it’s making your life difficult or isn’t doing something that you want it to then I’d say stick with it.
Unimproved basses generally hold their value more than most that have been tinkered with, so there’s that to consider if and when you want to upgrade to another bass down the line.
If you’re currently enjoying playing it then my advice would be to keep doing that.
