In dictionary 'nums' 1, 2 and 3 are keys.

so (key in nums) here 'in' is used to check 'key' exist or not

So 'three', 1 are key which you are checking in dictionary 'nums'

but 'three' not exist in 'nums' so it returns False

But 1 is exist in 'nums' so it returns True

'in' when used for dictionary, checks for keys.
if you want to check for values, use the .values() method:

print("three" in nums.values())
