Absolutely not. That would be an impossible job. You just have to remember that over the last century the size of the American government and its agencies and sub-agencies has grown along with our economy and population, so that the President has tens of thousands of employees to help maintain the government bureaucracy and its various tasks, and dozens of cabinet members, advisers and staffmembers to help him direct them all.
Luckily for the President, the vast majority of these programs are not new, have been running for a long time, and we have well trained personnel who make entire careers out of steering the ship, so to speak. All the President has to do is give them some direction when they need it, and make sure they are funded in the budget each year.
