Is it normal to have iPhone 10 gestures on an iPhone 7?

I recently bought an iPhone 7, but sometimes I can for example open my task manager by putting pressure on the left side of the screen. If it helps, I have the newest update. Is that normal? Is it a part of the new update? Or is my phone just glitching?

People at work make fun of me for having an older iPhone?

I work in an office and a lot of the people here are immature, I have an iPhone 5, I'm not really a big tech person, my iPhone 5 makes phone calls and lets me use the internet and that's all I really need, it works fine. People always tell me that it's old and stuff just because they have the newest iPhone, I've had mine for 6 years now and I think it's good that I don't waste money on a new phone every year if it still works but they call me poor and stuff. How should I deal with something like this? What are good comebacks?

Am I considered spoiled'?

I'm 18, a guy. I want to know if I'm considered spoiled. I have a job and I bought WITH MY OWN MONEY a new MacBook Pro, iPhone XS Max, AirPods, I bought my dad and I tickets to go see Queen with Adam Lambert. I also bought my own ticket to go see Lynyrd Skynyrd at the Concord Pavilion with my dad. But I payed him back. My dad got a new car and I got his 2016 GMC Yukon XL Denali. That thing has 30k miles on it. I have a job so I can afford it. Am I considered "spoiled"?
