No, zeroes can be significant digits

#### Explanation:

Zeros that are significant digits in the following cases are marked red:

• $5 \textcolor{red}{00} . \textcolor{red}{000}$
• $321.321 \textcolor{red}{00} 223 \textcolor{red}{00}$
• $5 \textcolor{red}{00} 3 \setminus . \textcolor{red}{0} 2$

The only times zeros are not significant are when they are leading zeros ($00223.23$, $0.0002123$), or are trailing zeros and if there is no decimal place ($200$, $238329500$).
