Wood is kind of pretty hard and the chain of the chainsaw is made of “blocks” I suppose, can’t really find out what it exactly is but anyway, to me, it seems like that chain would just get stuck in the wood at the very moment it touches it. Even more when cuting deeper into the tree.

A chainsaw is NOT made out of blocks. It is made of several sharp cutting teeth. Each of these teeth are “protected” by a secondary blunt tooth that pushes against the wood to make sure the cutting tooth does not try to bite… more than it can chew, by digging in too deep into the wood.
Finally the chainsaw can and definitely does jam all the time if you don’t throttle enough, push too hard against the wood or try to start while the saw is in contact with the wood (you have to let it run freely for a second before it catches enough speed not to jam).
A chain saw blade is mostly covered with cutting [teeth](https://bettertoolz.com/wp-content/uploads/2019/06/What-Are-The-Parts-Of-A-Chainsaw-Blade2_.jpg). But yes, a blade can jam but not due to the actual cutting. It is more common for the tree or whatever is being cut to pinch the blade, causing it to stop or bind. Wood is structurally strong (for the most part) but cuts fairly easily.
There are two sorts of blocks. One cuts on the left and one cuts on the right. The chain goes left-right-left-right-… . By cutting a slot that’s wider than the chain and the bar, it’s easy to avoid problems. Of course, you have to be smart, and but the tree in tension rather than compression. If you cut wrong, the blade will be pinched.
Key is the speed. Try it with a barely moving chain and it gets stuck. Get enough speed and the wood it gets stuck in can’t hold it and breaks, allowing the next block to eat a little more inside.
As the saw goes in, it goes in a straight plane and touches nothing else. From the saw perspective, it’s just the wood below it that is present. The rest doesn’t offer resistance. Also the sides of the blocks are relatively flat and can slide should there be a small misalignment. But torque it enough and it will surely Jam.
Edit key is the speed. Not isn’t.
