Is 19 and 17 too big of an age gap?

I'm 19 and I recently started talking to this girl from hinge. We got along super well and were texting 24/7 and I was really excited about what it could become. A week into texting she dropped the bomb that she lied on her profile and that she's actually 17, her birthday is in three months but she really likes me and wants to keep talking. I talked about it with all my friends and everyone has different opinions on what I should do. Some say hard no and others think I should keep talking to her. I feel like I'm on an emotional rollercoaster everyday. I go from thinking I'm a horrible person to smiling at her texts. I have no idea what to do. (For context I'm in my second year of uni and she's in her first year of cegep which is kind of like college where I live)
