When I Call An Anonymous Welfare Check On My Parents, What Will Happen?

The environment is pretty filthy. Mice infestation, animal feces, trash, mold. Humans and animals in unhealthy conditions. My younger brother is not educated properly, and neither am I, with both of us missing years of education. So what will happen? Hoping I'll get taken away immediately lol, but I know that won't happen which scares me because my parents will go crazy if they find out I called them.

update: not going through with it. Too scared, and I don't even know if it'll help anymore.

Update 2: thinking about talking to my grandparents about it. I was going to like a week ago, planned out a day to call with her and everything, but pussied out last second. I would love to live with them, but that probably won't happen so I'm still hesitant to talk to them. They're eventually just going to talk to my parents, and probably just tell them to clean up or whatever. Still won't be happy after that. I hate my mom, and hate how this family functions. It's not normal. I've only ever felt truly happy and normal living with my grandparents when they last visited in September.
