AWS WAF - Bot Protection Rules

Hello guys, we are looking for this WAF Rule in the AWS Marketplace.

We have interest in DDOS protection further, so can anyone tell me if the F5 Bot Protection Rules  could work and what "DDOS bot/tools protection means". 

We will use the WAF for ALB, se we need to cover the layer 7 and not sure which kind of protection this can give us? If some hackers pretend to make a DDOS attack trough our Load Balancer, will be covered?

"F5's Managed Rules for AWS WAF offer an additional layer of protection that can be easily applied to your AWS WAF. F5's Bot Protection rules analyze all incoming requests and block any malicious bot activities identified, including DDoS tools, vulnerability scanners, web scrapers, and forum spam tools"
