Yes. That is how it is and has been for 17 years. Perfectly safe and unlimited.
Player stations offer many things - better bonuses for industry, player-owned markets, strategic bases for wars or other campaigns (or resource collection), enabling things like moon mining, a player home… and probably more I am missing. They also have ‘Asset Safety’ where your stuff is perfectly safe as long as you keep them fueled, as well as unlimited storage.
Deploying a station is not something a new player should immediately aspire do, not even a solo player. They are designed to be contested and fought over, and best owned and protected by a group.
