Is this an early sign of toenail fungus?

Since I just realized my brother who I share a room house with has pretty bad toenail fungus, so I’ve been a bit paranoid about my own foot health. I looked closely at my toenails and noticed a little anomaly on the outward facing sides of both my big toe nails. I’m no expert, so I don’t know if this is the beginning of a foot decease or just a mark from them getting a bit too long or perhaps a birth mark
