Professionals also have a much more diverse set of goals, obligations, and restrictions. For example a professional running an SP500 index fund is not going to buy a great deal just because they can see it. Their goal is to track the SP500 and that is how they will decide which deals to do.

Even for non-index managed funds there are often objectives or restrictions like cap size, geographical location, industry, time horizon, etc.

So while they might have better tools, they're not necessarily competing with you directly.
