Being available for someone means that you have 'free' time and can fill it with something that is important to that person, if you feel like it.
Making yourself available to someone means that you intentionally commit to & protect that time, for their specific needs.
There's a huge difference.
Don't tell someone you're available if you're not willing to give them your time & attention. Sounding like a nice person by saying you're available doesn't help anyone. In fact, your co-workers or those under your leadership will eventually see the real you. They'll associate your frequent 'I'm available' with something along the lines of 'I have some free time, I wish I didn't, so please don't contact me unless you have an emergency.'
Take-away: I'm available = The time slot is free but I don't really want to fill it. I will make myself available = Whatever is important to you is important to me.
