i want to update my iOS to 13
Do you have an iPhone 6s, 6s Plus, SE (1st generation), 7, 7 Plus, 8, 8 Plus, X, XS, XS Max, or XR? If you have one of those iPhones, and you have kept it from automatically updating past iOS 12, your phone should be offering you an update now. It will not be to iOS 13 or 14, but to an appropriate higher version. You might need to use a Mac or PC to update your phone if you have been deferring updates for this long.
Frankly, I can't think of a reason why anyone with an iPhone that could update to iOS 15 (possibly later) would still be running iOS 12 (or earlier) after all this time.

If you have an iPhone 6 or 6 Plus, you cannot update to iOS 13. Those phones do not have the hardware required to run anything later than iOS 12. For one thing, they have only 1 GB of RAM. Every iPhone that is able to run later versions of iOS has at least 2 GB of RAM. I doubt that this is a coincidence.
If you want to run modern apps, you will need to get a newer iPhone, preferably one that's compatible with iOS 18.
