In Python, does "if" evaluates the conditional statements in boolean context? [duplicate]

I am new to programming so apologies for not being able to frame the question properly but here's a more detailed version of the problem. If I run the following code:

age=2
if age:
   print("hello")
else:
   print("bye")

Output is "hello" which I read was due to age being evaluated to True.

But when I modify it to:

age=2
if age is True:
   print("hello")
else:
   print("bye")

The Output is "bye"

I was expecting the Output here to be True. Where is the gap in my understanding? I Would also be grateful if you could direct me to a link to study the topic. Thanks
