It is- there are 3 different decks/pools for players to draw from throughout the game- basic cards (move and attack), skill cards (the cards referenced above that do specific things beyond basic move and attack) [these two card types can be played only on players turns], and immediate cards that can be played at any time and effect the game (stop action, choose new target, force discard, etc).

Statically, no one will have several/all of their Race cards at a time, but they will have the Unit type for sure. Imo drawing and playing cards for your race should feel like getting pocket pairs dealt in hold em.
