Yes, for decades. Move SSH off of port 22 and you’ll see far fewer attempts.
No idea why you are being downvoted, this is a solid advice. Masscan [1] claims to scan whole IPv4 Internet for a single port in 5 minutes. Moving to a random high port would increase scan time 64000-fold, to 7 months.
You'd still be advised to disable password-based auth and/or configure fail2ban, though.
