That is not asking for help. Asking for help would be "Can somebody please help me? ... rest of message here...". Even better is asking an individual (or individuals) directly.
Say what now? Mentioning you are blocked, in a stand-up, multiple times is a cry for help. What is the point of having stand-ups if you're not assisting blocked team members?
The standup is for blockers to be announced. It's the 3 stage of the standup.
Sounds like poor management, don't blame the new guy, he did say he was blocked in standup. How is he to know who to ask. Whose time can he impinge upon. It might be he asks someone who helps him but he gets in trouble because he now took up that persons time from something else.
The manager should see oh he is blocked, I'll assign so and so to help unblock him.
Comment sounds like typical 'pull yourself up by the bootstraps', meant to put down new talent, ignoring that complex, modern dev environments have many parts that are completely out of reach for newcomers without adequate onboarding.
Like you said, why not both? The employee is already asking for help, that's their part. The manager needs to come in and assist, unless he enjoys churning his dev team.
