I think the OS itself will be fine since the kernel and all that will be loaded to memory. But if you install games on that USB stick, they might be painful to run/load (depending on the game, some do disk reads while you’re playing, some do it all before the level).
If you have a free partition to install it on, try using it to install a game or two while using the live boot. Or hell, you could even just install the OS there and then nuke the partition if you decide against it. It wasn’t a long process iirc (with Fedora), most of my time was spent learning about what the implications of each choice were. If you’re just experimenting, those choices don’t matter as much (just don’t format your existing partitions).
Though they’ve also got USB external drives (HDD and SSD) that perform better than USB sticks. Some external SSDs probably still way outperform internal HDDs, even.
