In this post an your other post your code look messy when look at it for having good practice in Python.
So i rewrite it would look like this and code works.

import numpy as np

# Make random numpy array
mat = np.random.random((10,1))
mat2 = np.random.random((10,1))
mat3 = np.random.random((10,1))

my_dict = {"new_dict": {'mat1': mat, 'mat2': mat2}}
# dict to add
basic_dict = {'mat': mat}
new_key = 'new_key'
if not new_key in my_dict:
    print(f"{new_key} is not in my_dictList -> added")
    my_dict.update({new_key: {}, })
    my_dict.update(basic_dict)
else:
    print(f"{new_key} is in my_dict")

# Test my_dict
get_mat2 = my_dict['new_dict']['mat2']
print(get_mat2)
print('-' * 25)
print(my_dict)

Output:
new_key is not in my_dictList -> added
