Different behavior between running command with prefix sudo and as root user, seemingly sudo is less authorized

Question

I want to disable Address Space Layout Randomization(ASLR) by echoing 0 into /proc/sys/kernel/randomize_va_space. But I failed to do so in normal user mode even with prefix sudo:

$ cat /proc/sys/kernel/randomize_va_space
2
$ sudo echo 0 > /proc/sys/kernel/randomize_va_space
zsh: permission denied: /proc/sys/kernel/randomize_va_space

When I tried the same process after login as root user, I succeed.

$ su 
# cat /proc/sys/kernel/randomize_va_space
2
# echo 0 > /proc/sys/kernel/randomize_va_space
# cat /proc/sys/kernel/randomize_va_space
0

I wonder why commands running with prefix sudo failed but as root user succeed. What is the difference between sudo and root? I tried this experiment on a Linux system and a WSL and they all exhibit the same phenomenon. The two profiles of my experimented environments are
