Not true. Not true by far. That's an over statement. 2FA is only one of two factors, you need the the password, you need the mobile number and you need to obtain a duplicate or being close to your victim.
You should be worried if you are a POI or you are being targeted personally. And if it is so, SIM Swapping it's just one option and if it doesn't work there are other methods (breaking in, stealing yubikeys, mobiles...)
