Struggling with keeping up Gold income

Hi everyone. I'm a low elo player with experience with Age of Empires 2, 3, and 4.

I'm still trying to learn Age of Mythology. I'm having fun, but find that I struggle a lot with gold. While I'm used to gold being finite as in AoE2, I'm not used to just about every single military unit costing gold, in addition to research, upgrades, buildings, etc. I also understand that you need to rely on trade caravans, but I find that that doesn't really make up for just how much you gold is required.

Should the majority of my villagers be on gold? Should I prioritize gold more than any other resource?

Any advice?
