Why my system says have a 32 bit cpu?

When execute:

$ cat /sys/devices/system/cpu/modalias;
cpu:type:x86,ven0002fam0019mod0021:feature:,0000,

Says have a 32 bit cpu, but have a ryzen 7 5800X3D, is a 64 bit cpu, what happens?

$ cat /proc/cpuinfo | grep Ryzen | head -n 1
model name	: AMD Ryzen 7 5800X3D 8-Core Processor
$ uname -i
x86_64

modalias file is not the cpu architecture representation?
