Você não está utilizando o MySQL como no curso, então precisa alterar no pom.xml a dependência do MySQL para o MariaDB:

<dependency>
  <groupId>org.mariadb.jdbc</groupId>
  <artifactId>mariadb-java-client</artifactId>
  <scope>runtime</scope>
</dependency>

Deu certo, muito obrigado prof, agradeço demaissssss
