If you look at the photos on a big monitor, you can spot the difference between a DSLR and smartphone. But on a smartphone screen, where 95% of the photos are viewed these days, the difference is negligible. Heck my wife recently printed out 4x6 prints of her smartphone photos and they looked pretty good too.
I've recently got a iPhone 12 Pro, and it's good enough that I'm thinking of selling my Fuji X100V. DSLRs used to be accessible for amateurs. But unless you need specific capabilities (strobe usage, fast sport shooting, ultra-telephoto, etc), most people don't need to buy a DSLR if you have a decent smart phones these days.
