I watched my friend play Minecraft and it said that his fishing rod was 2 durability, but when he used it, it broke, so he asked me to complain lol.

From https://minecraft.fandom.com/wiki/Durability:

Fishing rods:

• Breaking a block or hitting a mob counts as 0 uses.
• Casting the line and reeling it in empty, counts as 0 uses.
• Reeling in an item counts as 1 use.
• Catching the bobber/hook on a block, then reeling it in, counts as 2 uses.
• Using the line to yank on an item counts as 3 uses.
• Using the line to yank on a mob counts as 5 uses.
