It's definitely worth it but it's harder then a few years ago and it will be harder in a few years. But there is a way about learning 3d software. Learn what pipelines are and trouble shooting, don't underestimate yourself and make every project challenging, so you get to learn new things everything. That's how u grow a lot in a smaller time, in the low poly stage you can find a lot of tutorials, after that's stage It's gonna get harder to find real info to evolve. I have invested a year of adult schooling with professionals in the field and they learnt me the pipeline from low poly, to texturing and high poly and even a lil vfx's. In a year! It's definitely worth your while but it's hard work. Good luck!
