Does a higher pka mean that it's more acidic?

the higher the pKa, the weaker the acid (less acidic)

No, strong acids would have a lower pka

A high pKa means a low Ka which means that a small amount of the acid molecules are deprotonated, making it a weak acid.
pKa=-log(Ka)

A higher pKa means a weaker acid since pKa is -log [acid]
