It's quite a common thing for people to perceive that modern mobile phone camera photos look better than equivalent dedicated DSLR or mirrorless camera photos., especially when viewed on screen at typical reproduction sizes. The reasons for that are that there's a lot of in-phone processing going on... strong noise reduction, equally strong sharpening, multiple shots merged to achieve higher dynamic range, etc.
DSLR and mirrorless cameras require more work from the photographer. There is more skill involved, both in taking and processing the photos. These cameras do offer the option of creating JPEG format files like your phone camera, and used wisely, they can produce good qualiy photos in a fairly wide range of circumstances. But the real power of a "proper" cameras (versus a phone camera) becomes apparent when shooting files in raw format and processing them with appropriate software.
If you compare the JPEG output of a phone camera vs a raw-to-JPEG processed photo from a DSLR or mirrorless camera, both at 100% reproduction, there is no contest. The latter will win every time. But there is a learning curve involved to get there. Bear in mind that it's quite possible to get phone camera results by processing a photo from a dedicated camera, but impossible to go in the opposite direction
