Look, here’s what it comes down to. If you value not having your professional career ruined, don’t risk it if you’re going to sell anything. It not only reflects poorly on your product, but on your ethics as a person if you’re willing to bring that kind of thing into a work environment, and may make people think twice before hiring you since it can then get -them- into trouble if you continue to use it for their project.
They all do the same things at the end of the day. Either get Blender for free or a budget tool like Maya LT or Modo Indie. The training costs that will go into making you competent in any of these programs will far outweigh the cost of the tools themselves regardless. With the tools being as cheap as they are now, and with the free options honestly being pretty compelling for hobbyists, there’s no reason to resort to piracy.
If you get into a legal battle with Autodesk or Adobe, they will take every penny you have and will ever make. Piracy lawsuits are often very inflated as an attempt to deter others, it can really ruin your life if you get caught. It’s not worth it.
