Trying to understand the use of escape character '\t' with print function

Question

I was playing around with print() and its end = "\t" argument with strings and integers. When I use integers inside, I don't seem to see the 'tab' effect at output.

Say,

print("Hello","mn", end="\t")
print("World")

Output:

Hello mn    World

But the below,

print("123","567", end="\t")
print("no!")

Output:

123 567 no!

That could be something dumb on my part, but I'm not sure what it could be. Thanks!
