Why the environment variables are not getting reflected upon user login?

Issue

• The below PATH variable is defined for the test user in the /home/test/.bash_profile file.

PATH=$PATH:$HOME/.local/bin:$HOME/bin
export PATH

Upon user login the echo $PATH shows the below output, which is correct as it is defined for this particular user in it's home directory.

[root@example]# su test
[test@example ~]$ echo $PATH
/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/test/.local/bin:/home/test/bin

However, when the other system users login they are fetching the same PATH variable.

[root@example]# su test2                                                                                       
[test2@example]$ echo $PATH                                                                               
/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/test/.local/bin:/home/test/bin  --> Observe the home directory,.

[test2@example]$ exit
exit

[root@example]# su test3
[test3@example]$ echo $PATH
/usr/local/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/home/test/.local/bin:/home/test/bin  -->  Observer, the home directory of 'test' user.
