is it easy to become a logistics/trucking dispatcher?

not talking about 911/emergency dispatch — mean the trucking/freight logistics kind. been looking into it as a possible side hustle/career option. anyone here actually done it or know someone who has?

trying to figure out:

do you need any certification or can you just get hired and trained on the job how much does experience in trucking/logistics actually matter to break in is remote dispatching (for trucking companies) a real thing or mostly a scam magnet what’s realistic pay like starting out vs after a year or two how stressful is it day to day

not trying to jump into anything blind, just weighing options. any real experiences or warnings welcome.
