It seems to me like Pre-order traversal and DFS are same as in both the cases we traverse till the leaf node in a depth wise fashion. Could anyone please correct me if I am wrong?
Thanks in advance!

Preorder Traversal is another variant of DFS. Where atomic operations in a recursive function, are as same as Inorder traversal but with a different order.
Depth First Search is equivalent to which of the traversal in the Binary Trees? Explanation: In Depth First Search, we explore all the nodes aggressively to one path and then backtrack to the node. Hence, it is equivalent to the pre-order traversal of a Binary Tree.
BFS is like - first go for my siblings then their child then their child and so on. pre-order DFS technique is generally used in graph traversal . BFS is a level order traversal in the case of tree. These four are different techniques of traversal and results are also different.
Pre-order is one type of DFS.
There are three types of depth-first traversal: pre-order, in-order, and post-order.

It won't be. Pre-order has a strict fashion of visiting the Left node and then the Right node. But for DFS it can be either as there is no strict fashion. So, more than one traversal exists based on what you push on the stack.
