You are correct. tree-sitter is not in competition with lsp; lsp is project wide (different files), so will do say code completion. tree-sitter is analyzing the current buffer and applying things like highlighting, brackets etc. lsp can do some of these tings as well, but sending the entire buffer over to the lsp server every time you want to update the buffer is an expensive operation. tree-sitter does it locally.
