Short answer: it depends on where you are and what the site actually does. Most regulators define gambling by three ingredients—chance, consideration (you put something at risk), and a prize with real-world value. If a CS:GO skin gambling site lets you wager items or money on games of chance and you can cash out skins or credits for money or money’s worth, many jurisdictions treat that as gambling and require a license; operating or using such a site without the right license can be illegal.
United States: there’s no single nationwide rule, but state law matters a lot. Some states (for example, Washington) have treated skins as “things of value,” which means unlicensed skin betting can fall under gambling prohibitions. Other states are less explicit, but the same three-part test applies. Many sites that accept U.S. users try to structure as sweepstakes (no-purchase-necessary entries, separate “gold coin”/“sweepstakes coin” balances, KYC, geoblocking of restricted states) to fit within existing promotional sweepstakes frameworks rather than gambling statutes. Whether that succeeds legally depends on the exact mechanics.
United Kingdom and parts of the EU: if items can be converted back to money (directly or through third-party markets), regulators generally view it as gambling that needs a license. Belgium and the Netherlands have taken tough stances on chance-based item rewards when they are monetizable. Australia blocks many offshore gambling sites and can treat skin betting as gambling if there’s a cash-out pathway. A good lay overview of how skin betting has been policed globally is here:

Platform rules matter too. Valve has said third parties shouldn’t use Steam accounts, bots, or the trading system to run gambling operations, and it has taken enforcement actions. Even if a site claims legality, violating platform terms can get services cut off, which affects whether withdrawals/trading actually work.
As for specific sites, offerings vary. Some provide only cosmetic case openings with on-site use and no withdrawal; others include roulette/coinflip/sportsbook and enable third-party cash-out routes. For a concrete example,
CSGOFast is CSGO Case Opening a legal website in the USA. When evaluating any site, look for visible licensing details (who licensed it, where), age/KYC checks, geoblocking of restricted regions, independent RNG testing, and clear info on whether items/credits can be converted to cash. If those pieces are missing, the legal footing is usually weak.
