AITAH or my nieces?

I 25F almost 26F have a bare minimum mom and dad who have shoved me in front of TVs, Computers, and Phones my whole life instead of spending time with me. Most of my book smarts come from the internet and TV and most of my basic life skills come from hands on experience by my coworkers, boyfriend, driving schools, and HR block. I plan to have enough money saved to move out of my mom and dads house by the end of this year and I am not proud to be an orphan aka someone without present parents in their lives.

I have two nieces though who are 25F and 19F who brag that they learned all their book smarts and life skills through the Internet and TV and the 19F one even said she learned how to drive by simply watching YouTube videos about it. Their mom and dad aka my sister and brother in law have often not been in their lives because they are infantilized, lazy, alcoholics, and drug addicts. Instead of desiring a mom and dad to teach them how to drive, cook, clean, bake, do laundry, and etc they said they only ever desired the internet and TV to teach them those things and they look down on people who only learn things through hands on experience. They also look down on people who want more than the bare minimum from their parents. Both of them say they want kids in the future which I dont think makes any sense since they think the TV and Internet should raise people instead of parents.

The both of them also say my mom is the only normal person in the family even though she provided the bare minimum and has four different kids with four different dudes because shes promiscuous.I cannot telling you how many times they have bragged about how awesome it is they were raised by the internet and TV. My nieces blame their parents absence as a simple drug and alcohol problem and nothing else. My grandmother who babies my sister is not blamed at all for her babying behavior and these two idiots brag about being orphans basically. I wish I wasn't an orphan so bad. My mom even offered to give me ownership of the house and I said I didn't want it. No amount of money could replace the absent parents. I hate my nieces so much for bragging about raising themselves. I want to tell them off on social media so bad when I move out and tell them to tattoo "I am proud to be an orphan" on their foreheads and that they should sterilize themselves. No amount of TV and Internet information could happily replace my desire for present parents in my life. Honestly I think absent parents belong in jail.
