Error importing aws credentials while using sudo python3 but not with python3

I'm a beginner to aws cli, boto and am working on an IoT project. Recently encountered this error that if I use sudo python3 and try to connect to s3, my connection is authenticated. But if I just use python3 I'm able to connect. Any ideas why this is happening?

Will I run into errors later if I need superuser permissions for my script? I am using internet over USB connection right now, and need the superuser command to run my code.
