Most monero users are on the desktop where the common practice is to download and run their own nodes and/or use monero from Android on apps like CakeWallet, where their node is used and assumed as trustworthy.
To give background info: most users are on desktops because monero mining happens using CPU and instead of GPU, so they install the wallet which comes with a miner included and installs the node as well. They basically make some little income every single day and accumulate that profit.
The other miners like GuPax also install a node on the local computer as well, so a large majority of users simply runs nodes locally because they don't want to send their hashes to remote nodes which might fool them.
