Hi,
On page 25 under the skills section it states "You can set your concept skills to a maximum of level 3, and other skills to a maximum of 1." So yes, a player could buy all their skills at 1 and get as many as possible, but even then, best case scenario they could only have 12 of the 16 available, as 12 is the most skill points any player can start with. Also note, the 3 point cap is mixed between general and advanced skills, and even though the above line says concept skills, I'm sure it's intended to refer to each subgroup as many skills unnecessarily overlap otherwise.
