Yes. DEXs like Uniswap are almost always more expensive to use than centralized exchanges.  That's mostly because DEXs work differently behind the scenes. They use an automated market maker (AMM) system to match orders and let users directly trade with each other using smart contracts instead of a company's servers.  To make those automatic trades happen, the network needs to use more computational power and that costs more in gas fees.  So while DEXs give people more control over their money, that freedom isn't free.  You've gotta pay the price with higher fees.  Whether it's worth it depends on what you value more - privacy and control or cost.
