Yes. Every die face has equal probability. Rolls use Math.random(), which is statistically uniform over many trials — enough for any tabletop game.

Can I roll with advantage or disadvantage?

Set the quantity to 2 d20s, then take the higher result for advantage or the lower for disadvantage.

Why isn’t this cryptographically secure?

Tabletop play does not require CSPRNG dice, and Math.random() is faster. For cryptographic draws (raffles, secret-sharing) use the Random Number Generator, which uses crypto.getRandomValues.
