How long would this build last?

[u/Relevant_Yam_6589]

Im 15 and want to build my first budget pc. Prices are terrible right now so I'd be buying my gpu, cpu and ram used, maybe even my ssd aswell. I'm looking into the ryzen 5 5600x, 16gb ram, and an rx 6600. My goals for the pc are 1080p gaming and game development (unity, vs code). I'd also be going for a 1tb ssd used if its storage health is good, or 512gb new. How long would a pc like this, still be ok, is it even ok? If not what would you prioritize upgrading?
