I am 24 years old and I am planing to get into mathematics sense it is essential In science. I have big plans and Math is the very first thing I want to focus on. I have very important question that won't let me rest. When I was young I didn't take math too seriously or school. I never memorized times table (multiple/divide). The rest I did on high-school and my scores were average of 80/100. Can I dive into mathematics without the times table in my memory?

The times table is a thing that you will require throughout your life, not only for studying mathematics or science but for day-to-day activities as well where there is the smallest bit of multiplication required.
As such, there is no compulsion for one to memorise the tables beforehand, but it helps a lot for doing complicated multiplications and for quick solution of elementary problems.... which is "widely regarded" as the signs of a sound mathematician.
So my advice would be that you mug up the time tables and do sums based on them. Believe me, if you work properly, in a month or so, the tables will be there in your head to stay forever. And after approximately $6$ months, you will notice that you do not have to recall or revise those tables at all. It will flow out of your pen like a stream of water whenever you start writing.
