You just need to orient yourself correctly.
Here is a neck diagram of a C major scale.
Here are two views of a C major chord

Think of this …
Were you to take a print out of TAB and place it flat on a desk, then place your guitar flat on the desk in the manner you play it, with you sitting at the desk, both would have the low E / thickest / 6th string nearest to you. The orientation of the TAB will not always be flat depending on whether you read it on a computer screen, a music stand or other. But the same principle applies regardless of the orientation.
Hope that helps.
